PHP 计算页面执行时间

?phpclass runtime{ var $StartTime = 0; var $StopTime = 0; function
get_澳门新葡亰网站注册,microtime() { list($usec, $sec) = explode(” ”, microtime());
return ((float)$usec + (float)$sec); } function start() {
$this-StartTime = $this-get_microtime(); } function stop() {
$this-StopTime = $this-get_microtime(); } function spent() { return
round(($this-StopTime – $this-StartTime) * 1000, 1); }}//例子$runtime=
new runtime;$runtime-start();//你的代码开始$a = 0;for($i=0; $i1000000;
$i++){ $a += $i;}//你的代码结束$runtime-stop();echo 页面执行时间:
.$runtime-spent(). 毫秒;?<
