php基准时间的代码示例

Here is a little example of how to benchmark or time something with php 这里有一段php代码，教大家如何去处理基准时间。

代码如下：

';
}

// the end time
$time_end = getmicrotime();

// subtract the start time from the end time to get the time taken
$time = $time_end - $time_start;

// echo a little message
echo '
Script ran for ' . round($time,2) .' seconds.';

?>

This will produce a list of numbers from 0 to 9999 in your browser and tell you how long it took too complete the iterations. 以上将产生一个从0到9999的数字列表，以及完成这些计算任务所消耗的时间。

总结：以上主要演示了microtime()函数的用法。
