实现方法一:
<?php /** * 获取页面执行时间 * edit www.jb200.com */ $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 style="color:#fff;background:#000;position:absolute;top:0px;right:0px;padding:3px 6px;">本次执行时间:', microtime(TRUE) - $this->microtime, '秒</div>'; else echo '<div style="color:#fff;background:#000;position:absolute;top:0px;right:0px;padding:3px 6px;">本次执行时间:', microtime(TRUE) - $_SERVER['REQUEST_TIME_FLOAT'], '秒</div>'; } }
另一种方法:
<? $pagestartime=microtime(); ?> <!--网页内容 start--> 网页内容 ... ... <!--网页内容 end--> <? $pageendtime = microtime(); $starttime = explode(" ",$pagestartime); $endtime = explode(" ",$pageendtime); $totaltime = $endtime[0]-$starttime[0]+$endtime[1]-$starttime[1]; $timecost = sprintf("%s",$totaltime); echo "页面运行时间: $timecost 秒"; ?>
