php代码运行时间查看类代码,主要是用来查看php代码的运行时间。
代码如下:
//date:2011-08-05
class RunTime//页面执行时间类
{
private $starttime;//页面开始执行时间
private $stoptime;//页面结束执行时间
private $spendtime;//页面执行花费时间
function getmicrotime()//获取返回当前微秒数的浮点数
{
list($usec,$sec)=explode(" ",microtime());
return ((float)$usec + (float)$sec);
}
function start()//页面开始执行函数,返回开始页面执行的时间
{
$this->starttime=$this->getmicrotime();
}
function end()//显示页面执行的时间
{
$this->stoptime=$this->getmicrotime();
$this->spendtime=$this->stoptime-$this->starttime;
//return round($this->spendtime,10);
}
function display()
{
//$this->end();
echo "
运行时间:".round($this->spendtime,10)."秒
";
}
}
/*调用方法
$timer=new Runtime();
$timer->start();
