復制代碼 代碼如下:

<?php
$t = new executeTime;
phpinfo();
class executeTime{
private $microtime;
public function __construct(){
$this->microtime = microtime(true);
}

public function getNow(){
$this->__dectruct();
}

public function __destruct(){
if (empty($_SERVER['REQUEST_TIME_FLOAT']))
echo '<div>本次執行時間：', microtime(TRUE) - $this->microtime, '秒</div>';
else
echo '<div>本次執行時間：', microtime(TRUE) - $_SERVER['REQUEST_TIME_FLOAT'], '秒</div>';
}
}
