Funny Session Behavior
I am writing a foto upload site. A PHP page displays the uploades
fotos an the customer can choose several things. The data of the fotos
are kept in an array called bilder. I keep the data in a session. When
the customer send the data the following code will be run:
if (isset($sendorder_x))
{
session_start();
$nachricht = $bemerkungen;
session_register(nachricht);
// echo "1.: ";
// print_r($bilder); // The array still exists in the session file
// echo "<br>
2.: ";
for ($i = 1; $i <= $bildanzahl; $i++)
{
$formatname = "formate" . substr("00" . $i, -2);
$copyname = "copy" . substr("00" . $i, -2);
$bilder[$i]->format = $$formatname;
$bilder[$i]->anzahl = $$copyname;
}
// print_r($bilder); // bilder[] exists with the changed data in the
session file
// echo "<br>
3.: ";
$briefporto = $porto;
session_register(briefporto);
// session_register(bilder);
// print_r($bilder);
// exit(); // bilder[] exists with the changed data in the session
file
// echo "<br>
";
header("Location: datenupdate.php");
}
The page datenupdate.php starts with the fololwing code:
<?php
session_start();
// print_r($bilder);
// exit(); // all data is in the session file, but the array bilder[]
is empty now!
include ("database.php");
$dbid = connect();
.....
You can read in the comments, what happens. The lines, which start
with commenst, are for debugging.
Has anyone an idea, what the reason for tis behavior is? BTW, I use
PHP 5.1.4, Apache Server 2 on WinXP prof. SP2
And: This is no Easter Egg :-).

Strange Session Behavior, Are Session Cookies Server Dependant
I'm having a strange problem with session variables. I am trying to access one of my site from two different systems. Sessions work fine on my system and I'm able to login but I cannot login from the other system because sessions are not working on it. On printing session ID i found out that my system keeps 1 session ID but the other systems doesn't, everytime I refresh it fetches a new session id. I have tried all browser settings but all goes in vain. Now heres the strange bit. We do have another server and we've got some sites running on it using the same session code for login. Sessions work fine for that server on both systems. Code:

Date Function Acting Funny
I'm using the date() function to generate each month name, but it's doing something really wierd!! It all works fine apart from 'February', it doesn't seem to like Feb v.much, and it just generates 'March' instead. I thought it might be my local server so I made a little file with that bit in it and uploaded it to my server, exactly the same screwy result. Code:

SQL INSERT Query Acting Funny
I feel like I've seen this before, but I can;t remember what the problem was... Anyway, I have the following INSERT query: $query = "INSERT INTO reference_no (month) VALUES ('" . $this_month . "')"; $result = mysql_query($query); The problem is that INSERT is not creating a new row -- instead it is writing over the last row in the table.... The SQL table should look something like this: ref_num month 1 3 2 3 3 3 4 3 ...and on in on in that pattern....ref_num is an auto-incrementing column, and I am repeatedly inserting a new row in which month is this numbered month (in this case, 3 = March)... My SQL table, on the other hand, looks like this: ref_num month 25 3 The ref_num indicates that there should be 25 rows in the table, but instead there is only one row, and the INSERT query writes over the previous row every time a new row is added...thus, leaving me with only the one row..

Odd Mt_srand Behavior
Apparently seeding mt_srand with different integers can produce identical series of mt_rand results. Specifically, every pair of consecutive even and odd numbers produces the same series - see below. This is a nuisance for me. Am I doing something wrong? I'm using PHP 4.3.4 on a windows box. mt_srand(0); echo " 0 new rnd =" . mt_rand() . " rnd =" . mt_rand() . " rnd =" . mt_rand() . "<BR>"; mt_srand(1); echo " 1 new rnd =" . mt_rand() . " rnd =" . mt_rand() . " rnd =" . mt_rand() . "<BR>"; mt_srand(2); echo " 2 new rnd =" . mt_rand() . " rnd =" . mt_rand() . " rnd =" . mt_rand() . "<BR>"; mt_srand(3); echo " 3 new rnd =" . mt_rand() . " rnd =" . mt_rand() . " rnd =" . mt_rand() . "<BR>"; mt_srand(4); echo " 4 new rnd =" . mt_rand() . " rnd =" . mt_rand() . " rnd =" . mt_rand() . "<BR>"; mt_srand(100000); echo " 100000 new rnd =" . mt_rand() . " rnd =" . mt_rand() . " rnd =" . mt_rand() . "<BR>"; mt_srand(100001); echo " 100001 new rnd =" . mt_rand() . " rnd =" . mt_rand() . " rnd =" . mt_rand() . "<BR>"; mt_srand(100002); echo " 100002 new rnd =" . mt_rand() . " rnd =" . mt_rand() .

Odd Fsockopen Behavior
Any IP address I try to open with fsockopen on a particular server seems to use another IP address instead. eg. I open a socket connection to 192.168.1.1 but the remote_addr that the other server sees is 192.168.1.255. It's as if, like I said, the IP address I supply to fsockopen is being replaced with another one. Anyway, this is breaking a script of mine. I don't think I can really do a lot in PHP to fix this but is there perhaps some way that I can detect it? Is there some command line parameter that I can pass to passthru or something that'll tell me whether or not such a thing is happening? Also, how is this even being done? Could a firewall do this? If so, I'm still not even sure how it'd be done...

Odd Cookie Behavior
I'm processing a form, and on the target posting page, I'm setting cookies for the name/value pairs like this: while (list($name, $value) = each($HTTP_POST_VARS)) { if ( $value <> NULL ) { setcookie($name,$value,time()+3600*24*30*12*10); $mystring = "<input type="hidden" value="$value" name="$name"> $mystring"; } } Now after posting when I go back to my original form with the same URL path, www.mydomain.com/mypath, I can see that the cookies are there because the values appear in the fields like we'd expect. However if I put the very same form in a different directory, eg: www.mydomain.com/secondpath then the cookied values no longer appear. I knew that cookies could be domain specific, but is there a setting that makes them somehow directory specific??

Array Behavior
I am trying to create a dropdown menu with options pulled from a MySQL database. I count the number of entries in the database, assign that to a variable, and then insert each entry into an array. I then try to echo the HTML for each option using this loop(where $numdisplayed is the number of times the loop has run, and $quotees is the array that the options for the dropdown menu are stored in.): while($numdisplayed < $numquotees){ echo '<option value="' echo"$quotees[$numdisplayed]"; echo'">' echo"$quotees[$numdisplayed]"; echo"</option>"; $numdisplayed++; } It seems as though you can't use a variable to refer to an array key. Any alternatives?

$PHP_SELF A Strange Behavior!?
As we know $PHP_SELF is a PHP predifined variable. It handles the current file name and extension. I have a file contains commonly used functions. it's named func.php. Inside some of these functions, I use $PHP_SELF. I perform include for this file in another file called index.php.The strange behavior is, in some code area $PHP_SELF does not return any value, in other word, it does not return index.php. However, in other areas it works properly! So What's the cause of this problem? Is it bug in my PHP? I use PHP Ver 4.2.3 on Apache, and windows ME. All this from phpdev423 package.

Strange Behavior With PHP Over HTTPS, On IE
I have a login.php and register.php inside our httpsdocs directory, that is the root of https:// path. login.php and register.php both require_once a global.php file located inside httpdocs, the root of http://. In Firefox and IE, viewing the page certificate of https://pathtosite/login.php will show our Equifax provider. But, only on Firefox does it show the 256 bit-encryption lock icon in the status bar of the browser. For some reason this isn't showing in IE. I created a blank index.php inside of httpsdocs, and accessed it at https://pathtosite/index.php, and in IE it shows the lock icon in the status bar. Very strange. Is it because the files are referencing to global.php, which is located outside of https? I wouldn't think so... or is this just an IE issue?

Lack Of Suexec Behavior
suexec on old perl cgi processes was useful: A cgi process (run by the apache process) could create files that belonged to me. Php usually runs as an '.so' library, owned by the apache process, which is more efficient. But it means all files (even in my filesystem space) created by php/apache end up owned by apache. This is an enormous pain the butt, particularly when complicated by 'safe_mode' restrictions. Why can't the php kernel be hacked to fork a full-fledged, separate process, that uses setuid owner for certain key file system chores: perhaps only for certain newly created functions, like "mkUserOwnedDir() or openUserOwnedFile()"

Classes: Strange Behavior
I have a problem with code like this (PHP 5.1.4): fila A.php: ======= include(B.php); class document extends obj { ......... } file B.php: ======= $GLOBALS['x']->new we(); function __autoload($class_name) { ...here is the code to load classes... } file C.php ======= class we extends obj { private $document; function __construct() { $this->document = new document(); } } The problem is that after loading A.php into browser, PHP cannot find document class which is defined in the A.php file! The problem is even more strange - if document class doesnt extends obj class than everything is ok. (The problem exact is that __autoload special function is called when in file C.php constructor of class we try to make the document object (all other classes like obj has been already loaded). Do you have any idea what is wrong with that?

What Is Php's Behavior When Connect To A Db?
What is php's behavior when connect to a db? I've been told that php was once a dominant web programing language. I've read a few chapters of a php book. I was wonder what's php's performance. Perl was once for a while a popular programming language for cgi. But start very process per one web visit cause serioius problem to system performance. And then FASTCGI born. I was impressed by its performance. But recently i learn to do some php program which connect a mysql db. It seems that the program run's very slow. So, I have 2 questions: 1. does the os need to fork a php interpreter for every single web request? 2. does the php connects to mysql all the time? that is does it need to connect mysql 100 times when a user request the url 100 times? If the answer if yes, i think that php's performance is unacceptable.

Strange Strtotime() Behavior

" - " . strtotime("+1 hour")); ?> outputs: 1097380666 - 1097308800 Strange strtotime("+1 hour") produced a time stamp less than the current time. It also never changes. In other words strtotime("+1 hour") always results in the time stamp 1097308800. I have also tried strtotime("+1 hour", time()) with the same result Is this correct, have I misunderstood the strtotime() function? I'm running Gentoo with kernal 2.6.8.1, php 5.0.1, apache2

Strange Class OOP Behavior
Anyone ever experienced this problem. When i pass a mysql result to the constructor of a class and use that resultset inside that class the original resultset outside the class gets affected too. That is not right i think because my result inside my class is private. Is this a bug? Can someone look at my code below please: <?php require_once('includes/connect.php'); class test { private $_result; private $_record; public function __construct($result) { $this->_result = $result; } public function show() { while($this->_record = mysql_fetch_array($this->_result)) { echo $this->_record['name'].'<br />' } } } # usage # sql statement dat artikels ophaald uit cartal database $SQL = "SELECT * FROM test_table"; # uitvoeren van dit statement $RESULT = mysql_query($SQL,$conn); $t = new test($RESULT); $t->show(); // mysql_data_seek($RESULT,0);..

Strange PHP_SELF Behavior
I am migrating a self-made CMS app from one linux server to another and i am getting very strange PHP_SELF behavior on the new server. This app uses SEF URLs like http://domain.com/index.php/title/4/ (4 being the id) When i use PHP_SELF in all the server but the new one i get as an answer "/index.php/title/4/". When i use it on the new server, i get "/title/4/"!!!!!!! I am at a loss here. What could be triggering such a change? What parameter should i change in the new server's config? For info purposes, i'll attach the PHPInfo for both servers: the working one and the new, not working one: NOT working server: http://new.microcar.es/phpinfo.php (PHP v4.3.11, Apache 1.3) working server: http://www.microcar.es/phpinfo.php (PHP v4.3.10, Apache 2.0) Hint: You could try http://new.microcar.es/phpinfo.php/title/4/ and see the result for yourself. last info: i tried under another 1.3 server and it works well.

Php Equivalent To Perl's || Behavior?
one feature of perl I'm desparately missing in php is using || to assign the first non-empty value in a list to a variable. For example, # perl example 1 $a = 1; $b = 2; $c = $a || $b; print $c; # displays 1 # perl example 2 $a = 1; $b = 2; $c = $d || $b; print $c; # displays 2, since $d is empty # perl example 3 $a = 'apple' $b = 'banana' $c = 'cherry' $d = $a || $b || $c; print $d; # displays 'apple' # perl example 4 $a = '' $b = '' $c = 'cherry' $d = $a || $b || $c; print $d; # displays 'cherry' This is such a handy language construct. Is there any such php equivalent that accomplishes this? I've already written a function to do it. (Like this: $d = value($a, $b, $c). But making value() visible everywhere is something I'd rather avoid if there's something built-in to php.)

Confusing POST Behavior -- Doing It Twice?
I am confused about what goes on with method POST. Here is an overview of a my code, sketching it out: <?php if (isset($_POST['Submit']) && $_POST['Submit']=="Submit") { ---Do a bunch of stuff--- if (isset($_SESSION['Error'])) unset($_SESSION['Error']); if (strcmp($A, "any") { // Verify that a Zip code is numeric and is five digits If (!is_numeric($_POST($zip)) strlen($_POST($zip)) != 5) then { $_SESSION['Error'] = "an error description"; header("Location: thisSite.php:); } } } header("Location: anotherSite.php:); ?> ...... in the form description I have an <?php if (isset(($_SESSION['Error'])) echo $_SESSION['Error']; ?> (Note: The form is type POST). So here is the problem: 1 - When I start, there is no error message. 2 - I deliberately put in a bad zip code and have a value other than "any" in the A control and click to submit it. 3 - Instead of going back to thisSite.php and displaying the error message, it goes to anotherSite.php. 4 - If I then hit the back arrow on the browser, it displays with the error message on thisSite.php It seems that 1 - on the submit it goes through the logic and sets the error. 2 - It then must be going through a second time, but this time taking on the default setting of "any" for control A and so bypass the logic on the zip code and so goes to anotherSite.php.

Text File Behavior
I have a question about the behavior of a text file thats being written and read to. Say Im using an XML file as the database for my little application. Users come to my site and the file is read and parsed and coverted to some display in html. On another page users can add information that updates this XML file. Is there any risk in this approach? While the XML file is being written to, what is its readabililty? And vise-versa. Assuming Im using the standard read write functions for files in PHP, will the read wait for a write to finish, etc.

Odd Behavior Installing Extension
I've set up PHP 5.0.5.5 on an Windows 2003 system running IIS (yes yes, have I considered Apache? Unable, other factors at play). I wrote a simple test PHP that does nothing but phpinfo(), and it works great. The moment I activate mysql support, trying to execute the script results in a perpetual wait until timeout. I have read http://www.php.net/manual/en/instal....extensions.php My libmysql.dll is accessible to paths (copied to Windows as experiment to make sure. My extensions_dir is pointed at my ext dir, and if I insert gibberish into it, launching PHP gives an error, so I know PHP has found and parsed the file. The crux is that things go to heck when I uncomment extension=php_mysql.dll. Trying to run the test.php halts and goes no further. If I comment that out again, everything works fine (except, of course, for mysql).

Stumped By This Php Database Behavior
Consider: while ($j < $num2) { $parent_id=mysql_result($result2,$j,"parent_id"); $fam_first_name=mysql_result($result2,$j,"fam_first_name"); $fam_age=mysql_result($result2,$j,"fam_age"); echo "it is $parent_id"; echo "<tr id=$parent_id>"; echo "<td></td>"; echo "<td >$fam_first_name</td>"; echo "<td>$fam_age</td>"; echo "</tr>"; ++$j; } The line that says "it is $parent_id" will print the variable. The next parent id will skip one if it has two of the same values. I know this may not make sense, but: it is 1 it is 3 it is 3 it is 6 but the second three from above will never be in the tr id= tag. i hope this makes sens. It just doesn't print in the tag if it has two rows.

Inconsistant Cookie Behavior
The idea is that the cookie should write the referrer information on whatever page the user lands on. The include for writing the cookie is included on every page of the site and has a conditional wrapper that essentially says don't write the cookie if the cookie exists. Thus should preserve the value of the first page the user lands on so that I can retrieve the information later. Unfortunately, sometimes the page written is not the first page of landing .. but rather the last page prior to the page that requests the cookie.

Normal Behavior W/ Slashes
Before anything is inserted into my site's DB, I run addslashes() on it. When the function is used, data in the DB looks exactly like it did when it was submitted. For example, if a user enters O'Reilly in a form, it will appear as O'Reilly in the database (when viewed in phpmyadmin, at least.) This seems to negate the need for stripslashes() when displaying text from the database, as there are no slashes in the string.

$_SERVER['HTTP_REFERER'] Strange Behavior.
I'm having trouble with referring a page across my site. My php uses a switch statement to see which action to use (if any): if(!empty($action_get)) { switch ($action_get) { case 'student_unassign': header('Location: ' . ERROR_FILE . '?error_id=2'); exit; break; default: header('Location: ' . ERROR_FILE . '?error_id=2'); exit; break; } } These two cases produce different results on the error.php page (defined as a constant for ERROR_FILE) I split out the referer array: $ref = $_SERVER['HTTP_REFERER']; $ref_arr = explode("/", $ref); $ref_count = count($ref_arr); $ref_url = $ref_arr[$ref_count-1]; and use $ref_url to display the referring page. case 'student_unassign': correctly displays where it's from (students.php) default: all the values are blank. Any idea what is causing this / how to fix it? Effectively I'm trying to positively validate the $action_get variable, and if it's not 'student_unassign', then redirect to the error.php page, creating a link for the user to return to the correct ("students.php") page.

Strange File Upload Behavior
I was having permission problems, so I'm using a test file to make sure uploading works. upload.php successfully uploads a file to the images/bookcovers dir: <html> <form method="post" enctype="multipart/form-data" action="upload.php"> <input type="file" name="userfile"> <input type="submit" value="submit"> <input type="text" name="eh" value='meh<'> </form> <?php $source = $_FILES['userfile']['tmp_name']; $dest = 'images/bookcovers/' . $_FILES['userfile']['name']; if ( ($source != 'none') && ($source != '' )) { move_uploaded_file( $source, $dest ); } ?> </html> Now, I use the same code in another php file. The file is in the same dir as the file above, and has the same permissions. The pertinent code is: $source = $_FILES['small_image']['tmp_name']; if ( ($source != 'none') && ($source != '' )) { $dest = explode(".", $_FILES['small_image']['name']); $dest = './images/bookcovers/' . $isbn . "_small." . $dest[1]; move_uploaded_file( $source, $dest ); $smallimg = 1; chmod($dest,0644); } When I try to upload a file using the second php script, I get permission errors: Warning: move_uploaded_file(./images/bookcovers/0679728759_small.jpg): failed to open stream: No such file or directory in /home/chucknet/public_html/bookclub/addBook.php on line 120 Warning: move_uploaded_file(): Unable to move '/tmp/phpw93I5U' to './images/bookcovers/0679728759_small.jpg' in /home/chucknet/public_html/bookclub/addBook.php on line 120 I'm really at a loss as to what could be causing this.

Strange Behavior With Phpmyadmin And Innodb Tables
I recently converted all my existing MyISAM tables to InnoDB tables through phpmyadmin. I noticed some strange behavior whenever I would refresh the screen, as phpmyadmin would report different numbers for the cardinality of the primary key (i.e. one minute it would say cardinality 388, then 244 on refresh, then something else), and it would report different values for the number of rows when mousing over the table names on the left menubar. This behavior only seems to exist on tables with a "larger" number of rows, and by larger I only mean ~100 or more rows (tables with fewer rows always report the correct number of rows). Whenever I do a SELECT *, I get the correct number of rows returned, so I know they are actually there.

Strange Behavior When Loading MySQLi Extension On Win32

Recently, however, when I upgraded from PHP 5.1 to PHP 5.2.0 and again when moving to 5.2.1, I noticed strange behavior when trying to load php_mysqli.dll. I am using Apache 2.2.3 on Windows XP Pro (32-bit). I use the php5apache2_2.dll to load PHP as an Apache module. The PHPIniDir directive in httpd.conf points to the correct directory. I also have the older php_mysql.dll extension loaded simultaneously, which works fine. However, in phpinfo(), MySQLi is nowhere to be found, and trying to use any mysqli functions or its class will yield an error saying that they're undefined. In php.ini, the extension_dir directive points to "C:php5ext". As for the environment, I have my PHP install dir in the _System_ PATH (it's been there for a long time): C:php5. When I install, I just move new release into the php5 directory, so necessary DLLs for extensions do not need to be moved, and older versions can be overwritten for newer releases. In fact, mb_string, mcrypt, GD2, cURL, php_mysql, and many other extensions load just fine. However, the only way I can get MySQLi to load correctly is by moving libmysql.dll into my C:WINDOWSsystem or C:WINDOWSsystem32 folders. I simply can't understand why the problem lies only with MySQLi. Also, when I restart Apache, there are no errors. The MySQLi extension directive in php.ini is also uncommented, by the way. :-) This has only started to happen since my past couple upgrades, so I'm not sure exactly what to make of that.

$_POST Behavior From Input=submit Vs Input-type=button
I have been trying to solve an annoying behavior with PHP (I think). Maybe some of you have encountered the same and have some ideas. I have an html form and I use an <input type="button"> element with the onClick event that calls a javascript funtion. Once the script's content has been processed, I execute the form.submit() directive. I would like to combine the html form and the PHP script into one, and use action="<?php echo($PHP_SELF) ?>". When the html form has <input type="button" name="theButton" value="thisisthetrigger" onclick="doThis(this.form)">but PHP cannot 'read' the value of $_POST["theButton"] after form.submit(). If I substitute the <input type="button"> for <input type="submit"> then PHP reads the value just fine. Some may argue to just use the latter option, but that will cost me a trip back to the server to basically do a lot of validation that can be very easily accomplished on the client side.

Session Problem: Session Exists, But Session Variables Don't Lasts
I have some troubles with session variables. I can easily create a session, but the variable I append to global session array ( $_SESSION) lasts only until the end of current function. I prepared an example that can demonstrate the problem (see code bellow): The program flow is this: (1) It starts with "session_start()" and displays "login_form()". (2) When user enters his username and password, it goes to "login()" function which sets $_SESSION variables. (3) This function also "Echoes" session_id and user name to the screen. (4) Then it goes to "MyProgram()" function. It only "Echoes" the same variables to the screen. Strange is, that the session_id is the same in (3) and (4), but the user name ($_SESSION["username"]) is only in (3), but not in (4). By other words - $_SESSION["username"] variable filled up by "login()" function is immediately cleared. I don't know why. There must be something missing, but after 3 days of watching it, I can not find a problem here. =========================================== <? Function login($uzivatel, $heslo) { $_SESSION["username"] = $uzivatel; $_SESSION["pass"] = $heslo; $U_Name=$_SESSION['username']; echo "Login username: $U_Name<BR>"; echo "Login session ID: "; echo session_id(); echo "<BR>"; } Function login_form() { echo ("<DIV ALIGN='center'> <H1>Test</H1> <P>Please enter your username and password:</P> <form action='test.php' method='get'> <INPUT TYPE='HIDDEN' NAME='login' VALUE=TRUE> <TABLE BORDER=Ɔ'> <TR> <TD ALIGN='right'><U>U</U>ser name:</TD> <TD><INPUT NAME='uzivatel' SIZE=25 ACCESSKEY='U' TYPE='TEXT'></TD> </TR> <TR> <TD align='right'><U>P</U>assword:</TD> <TD><INPUT NAME='heslo' SIZE=25 ACCESSKEY='P' TYPE='PASSWORD'></TD> </TR> <TR> <TD COLSPAN=2 ALIGN='RIGHT'><INPUT NAME='OK' ACCESSKEY='O' TYPE='SUBMIT' VALUE='OK' TABINDEX=3></TD> </TR> </TABLE> </FORM></DIV></HTML>"); } Function MyProgram() { $U_Name=$_SESSION['username']; echo "Program username: $U_Name<BR>"; echo "Program session ID: "; echo session_id(); echo "<BR>"; } { session_start(); if ($_SESSION['username']): MyProgram(); else: { if (!$login): login_form(0); else: login($uzivatel, $heslo); MyProgram(); endif; } endif; } ?> ===========================================

Code Is Secure Enough To Hold Of The Majority Of Session Fixation And Session Hijacking Attempts.
I am having a few problems dealing with the aspects of security on php pages, having read several books and looked at several web pages about it I am still having a few problems bringing it all together or finding a practical example... the following is what I am using, and would be very grateful if someone with the knowledge of such things could look at what I have used and tell me if the code is secure enough to hold of the majority of session fixation and session hijacking attempts. Code:

Warning: Session_start() [function.session-start]: Cannot Send Session Cache Limiter - Session_destory();
I'm getting this error: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent ... output started at blah blah blah.... on line 1. Line one is <?php session_start(); This page is a login and logout page. I use session_destory(); to log the user out when a link is clicked. It redirects them to this page, with a ?action=logout in the url. I use $_GET to test if action == logout, and if it does, it calls session_destory(); and then uses javascript to redirect the user after 5 seconds to the homepage. what does the error mean, I've seen it before, but for some reason it's not comming to me.
