PHP计算页面执行时间_[PHP教程]

PHP计算页面执行时间_[PHP教程]

以下类定义了一个计时器,将你的执行脚本加入到"容器"内即可(请看注释)

class timer
{ var StartTime = 0;
var
StopTime = 0;
var
TimeSpent = 0;
function
start(){
this->StartTime = microtime();}
function
stop(){
this->StopTime = microtime();}
function
spent(){
if (
this->TimeSpent) {
return
this->TimeSpent;
} else {
StartMicro = substr(this->StartTime,0,10);
StartSecond = substr(this->StartTime,11,10);
StopMicro  = substr(this->StopTime,0,10);
StopSecond = substr(this->StopTime,11,10);
start = doubleval(StartMicro) + StartSecond;
stop = doubleval(StopMicro) + StopSecond;
this->TimeSpent = stop - start;
return
substr(this->TimeSpent,0,8)."秒";
}
}
// end function spent();
}//end class timer;
//例子
timer = new timer;
timer->start();
/*
你的代码放在此处
*/
timer->stop();
echo
"执行本SCRIPT共".timer->spent();
?>
