How to use PHP to get program execution time _php tips

Adding "$stime =microtime (True)" in the default template is added to the head.htm; Gets the time the program started executing.

Copy Code code as follows:

<!--<?php
$stime =microtime (TRUE); Gets the time the program starts executing
$GuideFid [$fid]=str_replace ("<a href=" $webdb [Www_url] ' class= ' guide_menu ' >> home </a> "," ", $GuideFid [$ FID]);
$fupId =intval ($fupId);
$topMenu [$fupId]= ' CK ';
Print <<<eot

Copy Code code as follows:

<!--
EOT;
$etime =microtime (TRUE);//Gets the time the program execution ends
$total = $etime-$stime; Calculated difference
echo "<br/>[page Execution time: {$total}] seconds";
?>
