Uthaya:

What I ususally do is use a timer class.



<?php

//--------------------------------
//  Debug
//--------------------------------

class Debug
{
     function startTimer()
     {
         global $starttime;
         $mtime = microtime ();
         $mtime = explode (' ', $mtime);
         $mtime = $mtime[1] + $mtime[0];
         $starttime = $mtime;
     }
     function endTimer()
     {
         global $starttime;
         $mtime = microtime ();
         $mtime = explode (' ', $mtime);
         $mtime = $mtime[1] + $mtime[0];
         $endtime = $mtime;
         $totaltime = round (($endtime - $starttime), 5);
         return $totaltime;
     }
}


$Debug = new Debug;
$Debug->startTimer();


//page output here....

echp "<p>Page rendering time:&nbsp;". $Debug->endTimer() 
."&nbsp;seconds</p>";

?>
