PHP 计算页面执行时间

 

<?php
< ?
php
class runtime
{
  
var $StartTime = 0;
  
var $StopTime = 0;   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; $i&lt;1000000; $i++)
{
  
$a += $i;
}

//你的代码结束

$runtime->stop();
echo "页面执行时间: ".$runtime->spent()." 毫秒";

?>

   function get_microtime()
  
{
  
list($usec, $sec) = explode(' ', microtime());
  
return ((float)$usec + (float)$sec);
  
}
