How many users online in a web site?

[co.ador]

can you find out how many user online on any page trough firebug?

 

I am talking on a page where I won't have access to the host server?

What actually meant if it is possible to find another webpage or website numbers of user online?

Is this what your looking for?

 

<?php
session_start(); 

define("MAX_IDLE_TIME", 3); 

function getOnlineUsers(){ 

if ( $directory_handle = opendir( session_save_path() ) ) { 
$count = 0; 
while ( false !== ( $file = readdir( $directory_handle ) ) ) { 
if($file != '.' && $file != '..'){ 
if(time()- fileatime(session_save_path() . '\\' . $file) < MAX_IDLE_TIME * 60) { 
$count++; 
} 
} 
closedir($directory_handle); 
return $count; 
} else { 
return false; 
} 
} 
?

 

Then to display the numbers online you would use

 

<?php
echo 'Number of online users: ' . getOnlineUsers() . '<br />';
?>

Jiblix where should I put the code since I don't have access to the file where x website is. What program should I use becuase I don't have access to that file in other words is not my website is any website I search with a browser.

 

is firebug ok then where should I save this file?

 

Thanks you!

If you dont have access to the server, Im afraid you wont be able to save the script. Let alone operate it.

 

Its been a while since I have used UNIX but I believe you would need 777 privelages to properly run the script without error.

 

Sorry.

What you're looking for is just not possible unless the site already has a "Users Online" script uploaded...
