Hi, I am trying to loop a script every 10 seconds but am getting the following error: Fatal error: Maximum execution time of 60 seconds exceeded Part of the code is: <?php while (1) { echo "hello"; sleep(10); ob_flush; flush(); } ?> I have put echo "hello" just to test before adding the script. Is there a correct way to do this loop? also running this the page struggles and says it is still loading.

I'm trying to run a PHP script and want to have it execute when the user closes the browser. I have this code but it doesn't work. It runs when the page opens. Why doesn't it work? <html> <head> <script type="text/javascript" src="jquery-1.4.4.min.js"></script> </head> <body> <script type="text/javascript"> $(window).unload(function(){ alert("Goodbye!"); <?php $fp = fopen("counter.txt", "r"); $count = fread($fp, 1024); fclose($fp); $count = $count + 1; $fp = fopen("counter.txt", "w"); fwrite($fp, $count); fclose($fp); ?> }); </script> </body> </html>

body onload / onunload - how to run a php script?
strobic replied to strobic's topic in PHP Coding Help
Thanks, what i'm trying to achieve is a current online count of users on the page. This is stored in a text file. So when a user opens or closes the page it will increase and decrease the count. But I can't see how to amend this using Ajax to run the PHP script upon the javascript event. -
I have this code. Why aren't the php scripts working when executing the body onload or onunload functions? <head> <script language="javascript"> <?php function hello() { $fp = fopen("counter.txt", "r"); $count = fread($fp, 1024); fclose($fp); $count = $count + 1; echo "<p>Number of users online now:" . $count . "</p>"; $fp = fopen("counter.txt", "w"); fwrite($fp, $count); fclose($fp); alert("Welcome to My Page"); } ?> <?php function goodbye() { $fp = fopen("counter.txt", "r"); $count = fread($fp, 1024); fclose($fp); $count = $count - 1; $fp = fopen("counter.txt", "w"); fwrite($fp, $count); fclose($fp); alert("Goodbye!"); } ?> </script> </head> <body onload="hello()" onUnLoad="goodbye()"> </div> </body> </html>

Hi, I'm trying to code a page which displays the amount of users currently viewing a page. But how do I decrease the count if a user closes the page? Thanks
