PHP: Display page render time

June 12, 2009 2:06 pm /

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.
