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 

      $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.'; 

?>

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.
