timing the page load

[jpr]

Hey, whats the easies way to time how long it takes for a script to run?

Example:
created this page in 0.001727 seconds.

Thanx!

the PHP manual for the microtime function has a simple way of doing this:

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

$time_start = getmicrotime();

/ Do something /

$time_end = getmicrotime();
$time = $time_end - $time_start;

echo "script completed in $time seconds";

or using OO:

// timer class
class Timer {
	var $startTime,
		$endTime,
		$timeDifference;

function start() {
	$this->startTime = $this->currentTime();
}

function finish() {
	$this->endTime = $this->currentTime();
}

function getTime() {
	$this->timeDifference = $this->endTime - $this->startTime;
	return round($this->timeDifference, 5);
}

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

} 
// end timer class

$timer = new Timer(); 
$timer->start(); 

/***
* do something
***/

}

$timer->finish(); 
echo 'This page was generated in ' . $timer->getTime() . ' seconds.';
