PHP tutorial to determine the page execution time code
Determined the time required for the PHP script to execute the correct one microsecond.

Inserts the code at the top of the page:

<?php
$mtime = Microtime ();
$mtime = Explode (", $mtime);
$mtime = $mtime [1] + $mtime [0];
$starttime = $mtime;
?>
Then add the following at the bottom of the page:

<?php
$mtime = Microtime ();
$mtime = Explode ("", $mtime);
$mtime = $mtime [1] + $mtime [0];
$endtime = $mtime;
$totaltime = ($endtime-$starttime);
Echo ' This page is created in '. $totaltime. ' seconds. '
?>

PHP's Microtime () function returns the current UNIX timestamp microsecond.
