Checking "last Updated" On Remote Files.
How do I check the last updated time on remote files. I'd like my end result to be, a function that takes a list of urls, check the lastupdated date on that file (i.e., home page of someone's blog), so I can then grab the ten most recently updated among them, and print them, in descending order of update date.

Error In Page When Checking Http_get_vars("myvar") And "myvar" Was Not Passed In URL String
PHP, coming from ASP coding if (HTTP_GET_VARS['b']==1){ print "Yes"; }else{ print "No"; } when "b" is not passed via (http://www.mydomain.com?b=1 an error occurs and the "NO" is printed but an error is printed too. How can I check for the value of "b" so that no error occurs if b is not passed?? example http=www.mydomain.com $myvar=HTTP_GET_VARS['b'] causes an error because "b" does not exist (ie. its not passed in the URL string. $myvar maybe evaluated as NULL or Empty but the error is printed in the page, anyway.
Script For "updated Today" Blogroll?
Hi all - I'm new to PHP and I'm trying to make a page of blog links that show (1) the most recent posts for each blog, and (2) whether that blog was updated recently. I am happy to say I've accomplished objective #1 by using the magpie XML parser, and I now have a php page that links to the most recent blog posts from several blogs. My issue is with objective #2. I've seen some scripts that create blogrolls using blo.gs to show recency, but I don't want a whole blogroll - I just want a simple script that says something like "if the blog was updated today, do this, otherwise, do that". Is anyone familiar with such a script? Or do people have other ideas of how to do this?
Domain Checking Problem : $_SERVER["PHP_SELF"]
I'm trying to insert some html if the browser location is my top level domain (www.mydomain.com) only, and I have the following code which appears not to work :-( Can anyone cast an eye over it? <? $spacecheck = $_SERVER["PHP_SELF"] if $spacecheck = "/" { echo ('<td height="27"></td>') } else {} ?>
How Do I Do Something Like $color = ("red", "yellow", "blue")[$colornum]?
How do I take an index of a literal array, instead of a variable? That is, say I want to get the short name of a month. Can I do something like: $monthname = ("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec")[$month]; or do I always have to do: $blah = array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"); $monthname = $blah[$month]; It seems a shame to have to create a variable specifically for this one-shot purpose.
Checking An Array And "splitting It Up"
I'm trying to create an image upload class and got into a little array problem. (File is attached to post. Sorry for the Icelandic) I pass the $_FILES['someuploadfiles'] to $this->uploadskrar and then in skoda() I cycle through the array and the if/else sentence is to filter out the bad apples, the images that don't f meet the standards set, $this->ilagi_myndir is for pictures that meet the standards and $this->nilagi_myndir is for pictures that don't meet them. Those 2 arrays are are suppose to have the same structure as $this->uploadskrar and i'm not figuring out how.
Checking If $user & $pass = " "
if !( $user=="" || $pass==""); mysql_query("INSERT INTO users (id, sn, pw) VALUES ( '$idhigh + 1', '$user', '$pass')"); It wont load up my page when I try to run it with this in my page, what am I doing wrong? It checks my text boxes to see if the user and pass equals a blank input when the person clicks on the submit button, and if it does, then it does nothing.
Preventing Visitors Ability To "re-visit" A Page Via The "back Button"..
I have a rather complex registration/member sign up form.. which gets a little confused, when a visitor "backs" completely out of the form, then for whatever reason returns to the form. The form contains 'cancel' buttons, which naturally cancel the reg process and redirects them to the document just before they started. JS provides us with the "location.replace()" method, but I can't seem to find a way to coordinate the use of location.replace() with the posting of the form values. In short, I want to "replace" the first step of the form with the "second step". I think what's making this tricky, is that each step of the form are located within the "same" page (register.php). The document works like so: The first step is the "Member Agreement" when they click "agree" (submit) the system creates a new row in the temporary register table of the db. It then issues a registration cookie, which carries the row id, and session value. in addition (for those cookie impared users) we carry the row id and session value in hidden elements. So far, as long as the user continues through the process all is fine, but if they (for whatever reason) back all the way out, and click 'agree' again, the process fails. I guess I have to find a way to force a reload of the 1st step "if they've gone back" OR "replace()" the first step with the second, so as to prevent the user from going "back" to the 1st step of the register page.
Pagnation - Limit Number Of Pages Between "Previous" & "Next" Hyperlinks
Was hoping for some advice with a part of page navigation.... It works at the moment so there is a "Previous" & "Next" Hyperlink underneath the records. In between the Previous & Next links are the number of pages that there is of these records. e.g: Previous 1234 Next This is fine if there are only a few pages of records, but when there are hundreds of pages the numbers are listed and they take up half the web page with them. How can i make it so only limited 10 numbers of pages say appear between the "Previous" & "Next" Hyperlink and as you progress through the pages they are as do the next 10 numbers of pages? Code:
Uploading Large Files - Error "stat Failed"
I have a page where i can upload binary file (using the HTML input type=file approach). This works fine for relatively small files (<6MB)) but when files get bigger (13MB) there is a problem. The code of the php file is based upon the article in http://www.onlamp.com/pub/a/php/200...php_mysql.html: uploading large binary files using more than one table and more trhan 1 row per file. When I want to upload something of -say- 13MB the problems are: 1 takes ages to upload (slow connection? it's on my LAN), 2 after a while I get a error msg: "Warning: stat failed for none (errno=2 - No such file or directory) in /Users/marc/Sites/wwwweb/FTP/FileTransfer.php on line 91" Lines 90 and 91 are below: 90clearstatcache(); 91$time = filemtime($SrcPathFile); (does this mean the tmp file is not there???) I changed 4 variables in php.ini to accomodate the bigger file size: max_execution_time=120 post_max_size=65M upload_max_filesize=65M memory_limit =65M I changed the rights on the tmp file upload directory so that everyone can write to it just to be sure... Still I get the error. Why am I not able to upload those big files? Why does it take so long for the file to upload to the server? It happens all on my LAN (no proxies enabled) so it should be faster.... even dloading a file from the internet is faster than this.

[regex] Stripping Out "name" And "value" Values Out Of Tags, Aaargh
Searched through the site, but couldn't find the right regex syntax I was looking for. the thing i want is, to extract with preg_match_all the given values in a tag... ex. $str = '<input type="text" name="name" value="value">' $pattern = some magic stuff I need to know preg_match_all($pattern, $str, $result); And in result I want to have the values text, name and value AND it's important that the order doesn't matter so structure of tags can be <input type =name= value=> or <input name= class= value= type=> etc, etc...
'Parse Error' Problem In "isset" And "empty"
I've been having some problems with a parse error that I can't figure out (PHP 4.3.11 on Solaris9). Sample code: <?php // getting strange parse errors on this class A { var $value; function A() { $this->value = 1; } function getValue() { return $this->value; } } $a = new A(); if (!empty($a->getValue())) { echo "success"; } else { echo "failure"; } ?> The result of this is: Parse error: parse error, unexpected '(', expecting ')' in /foo/public_html/parse_errors.php on line 15 I also get the same effect with "isset", however, testing with "is_null" or "is_int" produces the correct ("success"/"failure") result. Any ideas?
How Can I Remove Session Files In The "tmp" Directory?
How Can I Remove Session Files In The "tmp" Directory? I have just started working with "sessions." A Unix server stores a temporary file in a "tmp" directory. The temporary files include a string of numbers for the sessions variable. I need to devise a way to remove the temporary sessions files from the "tmp" directory on the server. If you would, please respond and indicate: 1). What is the best way to remove the sessions files from the "tmp" directory? or 2). What is the best way to handle the sessions files in the "tmp" directory?
Mod_php And Reuse Of "include()"-d Files
while using mod_php in apache: If I am including one .inc file in one page, does it get compiled and kept in memory so when I include the same file in another page on the same server, the server won't have to search for it and recompile it ? does mod_php provide other advantages besides preloading the php interpretor/compiler in memory ?
Getting The Remote File Path From <input Type="file">
I'm using a form to upload a file to save in a mySQL database, however I need to store the original file path on the clients (the user uploading the file) computer. The file path is shown in the field that selects the file, I just need to post it or save it in a session somehow.
Echo "<!--#include File="top.html" -->";
I have a search script which returns a page of results, however I'd like the returned page to be in the same format as the rest of my site. To do this I've tried adding the HTML for my site to my PHP page with echo" " commands. This works for the plain HTML, but my regular pages also use SSI to do other stuff (some of them even execute other PHP scripts to generate tables of data etc). I've tried echo "<!--#include file="top.html" -->"; but it doesn't work as I get a parse error. My question is, how do I go about doing this properly? Is this possible at all? And if not have you guys got any suggestions to get around this?
Any File Size Limit In <PARAM Name="***" Value="***"> ?
I embed an applet in my php script which has a parameter providing an input file for the jar. Does this file has size limit? The code is as follows: <APPLET ARCHIVE="myapplet.jar" WIDTH=372 HEIGHT=360 VSPACE=0 HSPACE=0 ALIGN=middle> <?php echo "<PARAM NAME="data" VALUE="myfile.">";?> when "myfile" is beyond 15M, my applet cannot load sucessfully, but while this file is limited like 5M or 7M, it works well. Does anybody know is the reason caused by php script limit, applet mechanism, or by different browser?
How To Do PHP "require()" Or TCL "source" In Bash Script
I can't figure out how to explain this any better than this. In PHP we have a command "require()" that obtains a file and logically places it into another file. I cannot figure out how to do this in bash script as the requirement is necessary for a migration script to obtain the code from a .cfg file and then be able for the "parent" script to run the code it "imported" from the .cfg file, much like PHP's require() or TCL's "source". This is what I have so far and it fails: if [ -f ivc.cfg ]; then cat ivc.cfg fi Anyone really know bash script well please help, it's a barrier for me not to be able to get just this one piece working.
"Streaming" Image Files
I would like to stream image files from a directory so that the end user cannot see the actual file path of the image. For instance, I would have an image directory named "bob" and a PHP script/function that sends it to the browser like this: Code: <img src="someFunction.php?img=the_image_name.jpg"> I've seen this done with other languages, but how do you do it in PHP?
How To Move Files To The "lib" Folder?
A client recently asked me to move a lot of code into the "lib" folder...and I'm not sure exactly how to do this without having the site blow up. I'm using Subversion and have a root-level folder structure that looks like this: * lib * logs * sql * src Currently, I have all of my web files in the "src" folder. There is a folder of include files in the "src > includes" folder. The client is asking to move these to the "lib" folder for security reasons. How do I do this?! I'm not sure how to move files outside the "src" folder and have the site still function properly.
A "few" Old Session Files Never Deleted?
I have session files stored in a special tmp directory specific to a virtual host instance. The Max_lifetime is long 86400 (1 day) which I don't suppose is the problem. Anyway the sessions do indeed expire and "most" of the old session files disappear as expected. Not all however. I am finding several old session files with Unix last mod times weeks in the past. This behavior observed on PHP 4.2 and 4.3.
Writing PHP Files On The "fly"
Can anyone advise me of a method to have a file written in php on the fly from a mySQL database? Context: We are developing a content management system with PHP/MySQL and are working on some enhancements. We would like to emulate the tricks of cold-fusion which one of our developers knows how to use to accomplish this with. Is there a way to assemble data in a template style method but have it written to an actual page ie. thispage.php as opposed to using a dynamic url ie. .com/viewpage.php?folder=1,file=5,type=6 or whatever? If there is an existing resource where I can read about how this is done, etc. That would also be a fine answer.

Mysql/php - "LIMIT" And "ORDER"
In the following fragment of code, I am querying a database that in order to display a list of films. The list is very long and I would like to offer the possbility to restrain the range of results showned by page keeping in mind that the user should be able to browse forward or backward data if applicable. I know that I have to add the LIMIT method in the MySQL query but I have a hard time figuring how not to get lost in setting it dynamically in the PHP script. Then I have a second question. Is there a more elegant / straightforward way to deal with the display order of the data (cf. $ot, $od and $oy)? Code:
Sticking "if" Or Changes Within A MySQL "where" Array?
I'm not exactly sure how to even ask the question, and I know my terminology is not good as I'm a SQL beginner, but, here goes. I need to find a way to make an if statement within an array...or, the "while" portion of a recordset. The best way I can ask is show what I mean. http://oscarguy.mechphisto.net/awardbrowse.php If you go there and select an award (like Best Picture), leave the year field alone, and select YES and submit, you'll see a lot of results. And I have HR's dividing each entry. What I need to do is group all the entries of the same year, or at least only put HR's between the blocks of years. So, I'd have all the entries for 2002, an HR, then all for 2001, an HR, etc. Here at the bottom I'll include my PHP code I'm using so far. But I have no idea where to even start looking for an answer...if it's even possible. If someone can just give me the name of the function or process or technique, then I can go Web/book searching myself...I just need a direction of where to go. PHP:------------------------------------------------------------------------ ------ $query_RS_award = "SELECT * FROM $award WHERE id != Ƈ' ORDER BY year DESC, w DESC"; //$query_RS_award = "SELECT * FROM $award WHERE year = "$year""; $RS_award = @mysql_query($query_RS_award, $connection) or die("Couldn't query: " . mysql_error()); $totalRows_RS1 = mysql_num_rows($RS_award); while ($row_RS_award = mysql_fetch_assoc($RS_award)) { $award_id = $row_RS_award['id']; $award_tblid = $row_RS_award['tblid']; $award_award = $row_RS_award['award']; $award_year = $row_RS_award['year']; $award_category = $row_RS_award['category']; $award_won = $row_RS_award['w']; $award_film = $row_RS_award['film']; $award_nominee = $row_RS_award['nominee']; $award_note = $row_RS_award['note']; if (!($award_category)) { $award_category = "n/a"; } else { $award_category = $award_category; } if ($award_won == "1") { $award_won = " - Award Winner"; } else { $award_won = ""; } $display_block_Award .= "YEAR: <span class='normalText12White'>$award_year</span><br>FILM: <span class='normalText12White'>$award_film</span><br>CATEGORY: <span class='normalText12White'>$award_category</span><br>NOMINEE: <span class='normalText12White'>$award_nominee</span><span class='normalText12BoldWhite'>$award_won</span><br><blockquote><span class='normalText12White'>$award_note</span></blockquote><hr>"; }
Cookies And "include" Or "require"
i'm having a problem with my setcookie() instructions. Although there are absolutely no html tags in front of them,for some reason PHP3 sends me back the message "oops...php3_SetCookie called after header has been sent"... I do however use two "require" calls, one to a file with a .php extension, and one to a file with an .inc extension. At the beginning of each files there's a Could the cookie failure and the include functions be related ? In my text, I have even wiped out any HTML tags such as "bold, paragraph, line break" tags, even in "echo" commands, but to no avail what am i doing wrong ?

Make "blabla" Into Keywords As In "php.net/blabla"
I know this must be documented, but I cant seem to find it. How would you transform the URL into values? Like how php.net does; www.php.net/date does a search for "date" in their database...

Error Using Header("", FALSE) To Show Multiple Images From MySQL Db
Many people seems to have problems when displaying multiple images from their database (mySQL db). Often you can read error statements like "Header already sent out ...". To solve this, people often propose to use include files. To keep the scipt it would be nice not having this problem, being able to sent out multiple headers to a browser without getting these error messages. In the PHP4 manual, we can read an option that can be added to the header statement, Header("xxx",FALSE). It would enable multiple headers to be sent out. For instance the following statement: while ($product = db_fetch_object($result)) { header("Content-type: pv($product->filetype)",false); echo pv($product->image)" } However, it doesn't work. Anybody has any idea why? Does anybody use this option FALSE with success?
Reading An Array Of Records From MYSQL Then "Save As" Them Back As Copy
Hi all, Ok here is what I want to do then I will show you what I have. I have some records in a MySQL DB that I want to store in an array and then immediately copy them back where the only thing that would change would be one field - the date. So here is my table: ------------------------------------- |userName | date | value | -------------------------------------- | theDano | 200005 | 123 | -------------------------------------- | theDano | 200005 | 345 | -------------------------------------- | theDano | 200004 | 678 | -------------------------------------- | joeUser | 199908 | 897 | --------------------------------------- So if I am querying for the user "theDano" on a specific date (format yyyymm) in this case 200005 (year 2000 month of May) Here is my array to query all records to fullfill this request: if ($update=="future") { if ($month!="01") { $db = mysql_connect("localhost", "dbuser"); if($db) { mysql_select_db("dbName",$db); $result = mysql_query("SELECT * FROM tableName WHERE userName = '$userName' AND date = '$date' ORDER BY value DESC ",$db); if ($result) { $num=mysql_numrows($result); $i=0; while($i < $num) { $userName = mysql_result($result,$i,"userName"); $value = mysql_result($result,$i,"value"); echo "<tr>"; echo "<td width=Ê×'>" . $userName . "</td>"; echo "<td width=ï`'><div align='right'>" . $value . "</div></td>"; echo "</tr>"; ++$i; } } } } } Now I want to take the array of records queried which was: | theDano | 200005 | 123 | -------------------------------------- | theDano | 200005 | 345 | and copy them to look like this back into the database: | theDano | 200006 | 123 | -------------------------------------- | theDano | 200006 | 345 | so you can see that the only thing changed was increasing the month by one. Would seem simple to most but I am having a tough time wirting the code to read the array and increase each date value by "1". Thank you in advance for anyone that replies. ) Dano
Bizarre Phantom Bug (Calling A PHP Script From An Apache "Action" Directive)
I am using an "Action" directive in my Apache configuration to map a certain file type (by means of AddType and AddHandler) to a PHP script. I wasn't sure if this would work, since the Apache docs say the Action directive is for mapping a handler name to a CGI script in particular. But it seemed to work at first. Then a mysterious bug arose: Sometimes it works perfectly, and other times the output is a totally blank page. It seems that if I haven't viewed a page for a while, it chooses to do one of these at random (though it is blank more often than not), and then it persists in the same behaviour until I reload it many times. (That is, usually a page appearing blank will eventually display if I reload it many times; however, only rarely will a correctly-displayed page regress to appearing blank after reloads.) Checking with `curl -i', it would appear to a client program that the request was perfectly successful: all the headers are there (with the correct content-type), it has an HTTP/1.1 200 OK line, and so on (and there's nothing unusual in the server's access or error logs), except Content-length is 0, and there is indeed no content at all after the two newlines. WTF?? Since when do computers behave non-deterministically? I should hope, if a program is not going to behave correctly, that it at least do so predictably and consistently. That would make debugging it much easier. But what am I to make of this Schrodinger's Bug? How do I even approach the debugging process? (Also, if anyone could suggest a workaround, an alternate method of having a PHP script handle files with a certain extension, then that would be just as welcome. Though I'd like to stay within mod_php, avoiding a CGI-based technique, because I'd prefer to not start a process every time these pages are requested.)
Another "Fatal Error: Call To Undefined Function: Mysql_connect()"Question
I am getting the following error when I try to view a test page in my browser. This test page just reads a table in mysql and outputs the results. Fatal error: Call to undefined function: mysql_connect() in /var/web/public/test.php on line 2 I'm using: Apache 2 MySQL 4.1.12 PHP 4.4.0 I have tried upgrading PHP to PHP5. I went back down to PHP4. I verified that mysql.so was being loaded. I tried using the OLD_PASSWORD feature in mysql. Verified that the PHP module is loaded in apache. What is weird however (at least I think) is when I run the following via telnet: php ./test.php It pulls up the page, connects successfully to the database and displays the records. No error message.
