php中计算程序运行时间的类代码

PHP 2018-12-30

<div class="codetitle"><a style="CURSOR: pointer" data="40859" class="copybut" id="copybut40859" onclick="doCopy('code40859')"> 代码如下:

<div class="codebody" id="code40859">
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,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();
