启动和停止计时器 PHP
我需要一些有关在 PHP 中启动和停止计时器的信息.我需要测量从我的 .exe 程序开始(我在我的 php 脚本中使用 exec() 函数)到它完成执行并显示它花费的时间(以秒为单位)所用的时间.
I need some information regarding starting and stopping a timer in PHP. I need to measure the elapsed time from the start of my .exe program (I'm using exec() function in my php script) until it completes the execution and display the time it took in seconds.
我该怎么做?
推荐答案
你可以使用microtime 计算差异:
You can use microtime and calculate the difference:
$time_pre = microtime(true);
exec(...);
$time_post = microtime(true);
$exec_time = $time_post - $time_pre;
以下是 microtime 的 PHP 文档:http://php.net/manual/en/function.microtime.php
