一個(gè)可以統(tǒng)計(jì)你程序的運(yùn)行時(shí)間長(zhǎng)知的php類,實(shí)例代碼如下:
- class Timer {
- private $StartTime = 0;//程序運(yùn)行開始時(shí)間
- private $StopTime = 0;//程序運(yùn)行結(jié)束時(shí)間
- private $TimeSpent = 0;//程序運(yùn)行花費(fèi)時(shí)間
- function start(){//程序運(yùn)行開始
- $this->StartTime = microtime();
- }
- function stop(){//程序運(yùn)行結(jié)束
- $this->StopTime = microtime();
- }
- function spent(){//程序運(yùn)行花費(fèi)的時(shí)間
- if ($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";//返回獲取到的程序運(yùn)行時(shí)間差
- }
- }
- }
- $timer = new Timer();
- $timer->start();
- //...程序運(yùn)行的代碼
- $timer->stop();
- echo "程序運(yùn)行時(shí)間為:".$timer->spent();
