Invoke a prgram and calculate its process execution time thr
Hi all,

I want to invoke one program through php. I just get
the pid of that file and calculate its execution
time.

Guide me to invoke the program and calculate the
cpu(process) execution time.

Thanks and regards
uthaya

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>";

?>
