PHP: Display page render time

Home » PHP

12 June 2009 2 Comments

Here’s what I currently use to determine how long it takes to generate a page in PHP. Its only 4 lines of code.

PHP 5

$time_start = microtime(true); $time_end = microtime(true); $time = $time_end - $time_start; echo "Displaying the render time: $time seconds\n";

PHP 4 Version: (8 lines)

Put this at the top of the PHP script:
$render_time_start = microtime_float();

Put this at the end of the script:
$render_time_end = microtime_float(); $render_time = $render_time_end - $render_time_start; echo $render_time;

function microtime_float(){ list($usec, $sec) = explode(" ", microtime()); return ((float)$usec + (float)$sec); }

isnt your microtime_float function just the same as microtime(true) ?

I’ve updated the script for PHP5. PHP4 didn’t have the true parameter, so thats what the float function was for. Thanks.
