Outputs the time in seconds that it takes for a PHP page to load.
<?php
// Insert this block of code at the very top of your page:
$time = microtime();
$time = explode(" ", $time);
$time = $time[1] + $time[0];
$start = $time;
// Place this part at the very end of your page
$time = microtime();
$time = explode(" ", $time);
$time = $time[1] + $time[0];
$finish = $time;
$totaltime = ($finish - $start);
printf ("This page took %f seconds to load.", $totaltime);
?>
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.
<?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.
