Creating a PHP Script Timer
This timer is the simplest and easiest to implement. It will determine the time taken for a php script to execute correct to 0.000000000000001 seconds.
<!-- put this at the top of the page -->PHP's microtime() function returns the current Unix timestamp with microseconds. And the explode( string separator, string string [, int limit] ) function returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string separator. If limit is set, the returned array will contain a maximum of limit elements with the last element containing the rest of string.
<?php
$mtime = microtime();
$mtime = explode(' ', $mtime);
$mtime = $mtime[1] + $mtime[0];
$starttime = $mtime;
?>
<!-- put other code and html in here -->
<!-- put this code at the bottom of the page -->
<?php
$mtime = microtime();
$mtime = explode(" ", $mtime);
$mtime = $mtime[1] + $mtime[0];
$endtime = $mtime;
$totaltime = ($endtime - $starttime);
echo 'This page was created in ' .$totaltime. ' seconds.';
?>
