一个可以统计你程序的运行时间长知的php类,有需要的朋友可参考一下。

<script>ec(2);</script>
 代码如下 复制代码
class Timer { 
    private $StartTime = 0;//程序运行开始时间
    private $StopTime  = 0;//程序运行结束时间
    private $TimeSpent = 0;//程序运行花费时间
    function start(){//程序运行开始
        $this->StartTime = microtime(); 
    } 
    function stop(){//程序运行结束
        $this->StopTime = microtime(); 
    } 
    function spent(){//程序运行花费的时间
        if ($this->TimeSpent) { 
            return $this->TimeSpent; 
        } else {
         list($StartMicro, $StartSecond) = explode(" ", $this->StartTime);
         list($StopMicro, $StopSecond) = explode(" ", $this->StopTime);
            $start = doubleval($StartMicro) + $StartSecond;
            $stop = doubleval($StopMicro) + $StopSecond;
            $this->TimeSpent = $stop - $start;
            return substr($this->TimeSpent,0,8)."秒";//返回获取到的程序运行时间差
        } 
    } 

$timer = new Timer(); 
$timer->start();
//...程序运行的代码
$timer->stop();
echo "程序运行时间为:".$timer->spent();
