A simple "StopWatch" class to measure PHP execution time. The class can handle multiple separate timers at the same time.
<?php
class StopWatch {
/**
* @var $start float The start time of the StopWatch
*/
private static $startTimes = array();
/**
* Start the timer
*
* @param $timerName string The name of the timer
* @return void
*/
public static function start($timerName = 'default') {
self::$startTimes[$timerName] = microtime(true);
}
/**
* Get the elapsed time in seconds
*
* @param $timerName string The name of the timer to start
* @return float The elapsed time since start() was called
*/
public static function elapsed($timerName = 'default') {
return microtime(true) - self::$startTimes[$timerName];
}
}

Usage:

<?php
  StopWatch::start();
  sleep(5); // perform long running operation
  echo sprintf("Operation completed in %s seconds", StopWatch::elapsed());
