It displays how many users requiestd this page in past few minutes.
Simpliest way to do it is write down IP address and time of request.
something like

$data=file_get_contents("counter.dat");
$counter=unserialize($data);
$counter[$_SERVER['REMOTE_ADDR']]=time();
foreach ($counter as $key = > $value) if ($value < (time()-180)) unset $counter($k);
$data=serialize($counter);
file_put_contents("counter.dat", $data);

echo count($counter)." viewing"; 

it is just raw example. not a real code. locks must be taken inaccount.

Now There is a parse error some where in the line below.

Parse error: parse error, expecting `')'' in

Code where the parse error is

 $data=file_get_contents("counter.dat");$counter=unserialize($data);$counter[$_SERVER['REMOTE_ADDR']]=time();foreach ($counter as $key = >

Do I have to download the counter.dat file before using the code?

Yes my bad. There is mistake.
But if you don't know PHP syntax, this code isn't for you. It is just example, shows the way. Not a real code to put into site.

I have found this script php counter, but it is displaying a parse error on line 77 see the commented 77 line. My limited eyes doesn't notice any parse error can you see any?

Thank you..

<?php  
 session_start(); 

/* Define how long the maximum amount of time the session can be inactive. */ 
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 != '..'){ 
// Comment the 'if(...){' and '}' lines if you get a significant amount of traffic 
if(time()- fileatime(session_save_path() . '\\' . $file) < MAX_IDLE_TIME * 60) { 
$count++; 
} 
} 
closedir($directory_handle); 

return $count; 

} 
else { // line 77 where the parse error is
return false; 
} 

} 

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