Windows Program Command Exists
I can do this so easily in Unix: PHP Code:
$msg = exec('whatis convert 2>&1');
echo $msg;
However, in Windows using MS-DOS, I'm utterly lost. I am having to find out if ImageMagick is installed on a system for a function to operate (ImageMagick is required), and since this is a portable web application, you simply can't install ImageMagick everywhere you go.
Therefore I need to know if the system home has ImageMagick or not, and in Unix, I simply do a "whatis convert" and I can tell, but since MS-DOS has no equivalent to "whatis" I can't figure it out, and just running the "convert" command within a recursive function onto thousands of images is just not a good idea.

How Do I Make Sure That An External Program Does Actually Exists?
web host said there is a program /usr/bin/convert I can use to convert image files, after I call it in my code, it does not seemed to be doing anything. I'm sure the command line is right because I echo the commandline to make sure. How do I make sure that an external program does actually exists? I use if (file_exists "/usr/bin/convert")), is there any othe way? Or am I doing something wrong that the system call is not working? For example: //convert test.jpg to converted.jpg $command = "/usr/bin/convert "test.jpg" "converted.jpg""; echo $command; system($command);

File EXISTS Command With QUERY ?
i have a file exists on my page. It check to see if there is a picture of the product. If it exists, then it displays the item. It works just fine. I recently got a paging system to work to split the query results into numerous pages. Now here is how it normaly works QUERY IF FILE EXISTS - display item now here is how the paging system works.. QUERY - AND COUNT # OF ROWS MATCHING DATA QUERY - split rows of matching data by PAGE LIMIT, etc. NOW, the problem is when you mix them, the file exists works, but on the page #'s on the bottom counts ALL ITEMS MATCHING QUERY, just doesnt display them because of the file exists. My question is to know if there is a way do the FILE EXISTS in conjunction with the paging system. so for example. i have 40 items in database, 4 of them have pics. Paging system shows 4 per page... so the query finds all 40 items that match criteria and divides them my page limit (4) so you get 20 pages. So the first page has the 4 items with pictures, then the last 19 pages display nothing because the FILE EXISTS is over riding it.

Execute A Windows Program From An Anchor Tag
I believe I am close but I have spent several hours investigating this and can't understand why it won't work. I have tried exec, system, and settled on popen from reading various notes on the subject. I am wanting to launch a file editor when I click on a link. This is strictly an internal application so I don't need to worry about escaping shell/args. This is what seems as if it should work, however it doesn't. This is on XP, latest Apache 1.3.29 and PHP. The logic makes it into the "if" test and the file exists. Thanks. if (chdir("C:Program FilesTextPad 4")) { $cmd = "start "textpad.exe" x:webprogram.php"; pclose(popen($cmd, "r")); }

Php Session Problems When Working With A Windows Client Program
I am currently involved in a project that involves a windows client program written in delphi and a web application written in php. I have made several php pages for the delphi program to do requests via the http component from INDY. the problems I am having are: 1) the first request from delphi app to php web app is the authenication. In which user sends username + password to the php app. If authenication is valid, a session is started and the sid is returned to the client. All subsequent requests from delphi app to php web app will have this sid as one of the arguments in the POST form request (this is one of the function in the INDY component for delphi). Even the sid is passed to the subsequent pages, the session global array is still undefined. However if I open up a web browser and create my own string request to the login page then the next page, the global array would be defined (using var_dump + echo to see the array) what is the problem? 2) does the above problem has anything to do with the http referer field? 3) this problem that I am having has been asked before on google group, but somehow the person who asked it didnt' put down the solution for it. (this only involves the web only) when I login on a page and return with a session id, then I log out.. the user is redirected to the login page again. However if the user login again (with a different login account), he would be presented with the same session ID as before. a different sesson id is presented only if the user restart the browser. why is that happening?

UPDATE Command Is Not Working On MySQL, Windows 2000 Server
Hi all, I encountered mysterious problem with MySQL and PHP. UPDATE command is not working on MySQL configured on Apache 2 with Windows 2000 Server. It pulled my hairs for atleast 5 hours.

System(); Command Not Working On Remote System. Windows.
My server is a windows machine, on the same domain as python(also a windows machine). Apache is running as a service as an administrator. This is a test only environment to whom it may concern(I hate people telling me how insecure my system is) I'm just trying to run: $last_line = exec('dir pythonc$', $retval, $g); print_r($retval); echo '<br>'.$g.'<br>'; echo '$last_line= '.$last_line.'<br>'; Which outputs: Array ( ) 1 $last_line= The command from the command line works fine. And apache can access directories that only administrators can access on the local machine.

Method Name Exists, Property Value Exists, Calling Method Fails
I have a class object I am calling in another class: class Stuff { var $myObj; function Stuff($myObj) { $this->myObj = $myObj; } function doStuff() { print_r(get_class_methods($this->myObj)); print_r("<P>"); print_r($this->myObj->name . "<P>"); print_r($this->myObj->getName() . "<P>"); } } The first "print_r" works just fine and shows a "getName" method in the array of methods for object $this->myObj. The second "print_r" works just fine and shows the property value that was set in a prior $whateverObjName->setName('Whatever'); the value comes up as "Whatever". BUT the third print_r throws a nasty error "Member function called on a non-object". What happened? How did it turn from being a legitimate object to a NON-object in one line? Could someone with some class experience point me in the right direction as far as using "getter" functions of one object inside another object function?

Tracert :: Passing Command To Command Prompt Via Exec
I want to execute a "tracert" command in the command prompt via php (using windows) I've managed to use passthru() to open the command prompt (but it doesn't allow me to use it) and when I close it, it outputs the command prompt output in the browser. I don't mind whether the result is passed back to the browser to stays in the command prompt window (but that would use exec() I would think). So how can I tell the command prompt that launches to execute the line tracert 192.190.201.273 So far my experimental code is: <?php passthru("c:windowssystem32cmd.exe"); ?> EDIT: my backslashes have been stripped from the path, but you know what I mean!

Value Exists In SQL DB
I have this code that someone had made for me to add money into an account in my DB. Now I have found that it still adds the money if the account number does not exist in the database. I need to check if the account number exists in the DB and if so add the money if not return an error, I know how I would go about this in VB, but I'm not quite sure about the PHP. Here is my code: if ((isset($HTTP_POST_VARS["MM_insert"])) && ($HTTP_POST_VARS["MM_insert"] == "form1")) { $add_balanceSQL = sprintf("UPDATE account_info SET balance = balance + %s WHERE acc_no=%s", GetSQLValueString($_POST['NewMoney'], "text"), GetSQLValueString($_POST['AccountNumber'], "text")); mysql_select_db($database_billingserver, $billingserver); $Result1 = mysql_query($add_balanceSQL, $billingserver) or die(mysql_error()); }

How To Know If A Picture Exists Or Not
im trying to get custom pictures on my website based on how the user was directed there. i.e. if he clicked a link that says www.mysite.com/index.php?key=Gears%20Of%20War i use key to find "Gears of War.jpg" and display it on the page. Alot of the links that visitors may click will not have a picture designated for them, so i want a default picture to show when "Gears of War.jpg" does not exist. im assuming i need an if statement of some sort. How exactly would i go about doing this?

FTP > File Exists?
I am downloading the latest file from an FTP server. Fortunately the files are named with the date: 20051107_blah.csv (Created every working week day. I have some simple code which connects to the server, moves to the right directory, then creates the filename from the current date. It first tries 'today', then creates the filename for the previous day, etc. within a loop limiting it to a week. When a file has been successfully copied it then continues as desired. The problem is that my code outputs errors, visible to the user, and naturally I don't want them to see. Is there a way to see if a file exists without getting these visible errors?

Check To See If Image Exists
I've tried three different methods of checking whether an image on a server (sometimes my own, sometimes somebody else's) exists, and I'm not getting consistent results. Method 1: if (@fclose(@fopen("$burl", "r"))) Method 2: if (file_exists($$burl)) Method 3: if ($img = @GetImageSize("$burl")) where $burl is an absolute URL to an image. Methods 1 and 3 seem to return the same result, but Method 2 (as per the PHP Manual) always seems to return a "not found". However, the strange thing is that all three methods sometimes return a "not found", even when the image does exist. For example, here's such a banner: http://www.is1.example.com/cgd.aspx?BID=18457&AfID=100845&AdID=2941 Is this because this banner is actually returned by some code on the the hosting server, and if so, is there any way around this (other than trying to copy the banner to my own server - although in this particular case, I can't do that either)? (The reason I need it is that I have about 280 banners in rotation across several of my websites, and I have written a program that will check them all, switching them off or on as required, and emailing the results to me. If I can't find a consistent and accurate method of finding whether the image is currently working or not, I may have to go back to checking them all manually.)
