以下类定义了一个计时器,将你的执行脚本加入到"容器"内即可(请看注释)

class timer

{ var $StartTime = 0;

var $StopTime = 0;

var $TimeSpent = 0;

function start(){

$this->StartTime = microtime();}

function stop(){

$this->StopTime　= microtime();}

function spent(){

if ($this->TimeSpent) {

return $this->TimeSpent;

} else {

$StartMicro = substr($this->StartTime,0,10);

$StartSecond = substr($this->StartTime,11,10);

$StopMicro　 = substr($this->StopTime,0,10);

$StopSecond　= substr($this->StopTime,11,10);

$start = doubleval($StartMicro) + $StartSecond;

$stop　= doubleval($StopMicro) + $StopSecond;

$this->TimeSpent = $stop - $start;

return substr($this->TimeSpent,0,8)."秒";

}

}// end function spent();

}//end class timer;

//例子

$timer = new timer;

$timer->start();

/*

你的代码放在此处

*/

$timer->stop();

echo "执行本SCRIPT共".$timer->spent();
