Display Page Execution Time Using Php

Use this Small code to check the execution time of your script.

<?php
// Write this line at the top of script
$start = (float) array_sum(explode(‘ ‘,microtime()));

/*
your code here
*/

// Write these lines at the bottom of script
$end = (float) array_sum(explode(‘ ‘,microtime()));
echo sprintf(“%.4f”, ($end-$start));
?>

If you want to increase the execution time limit then use these:

1. set_time_limit(int $seconds)

(See it – will not work in Safe Mode)

2. ini_set(‘max_execution_time’, 300); //300 seconds = 5 minutes

(See it – ini_set will not work in Safe Mode)

3. Via .htaccess

php_value max_execution_time 90

4. Also set php.ini - This maximum execution time limit is set inside the php.ini file like this.
max_execution_time = 30; Maximum execution time of each script, in seconds



For Example


<!--  this  code at the top of the page -->
<?php
   $mtime = microtime();
   $mtime = explode(" ",$mtime);
   $mtime = $mtime[1] + $mtime[0];
   $starttime = $mtime;
;?>



<!--  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";
;?>

output
This page was created in 0.0027 seconds.
