4 个解决方案

#1

Call microtime(true) function to fetch current time with milisecond resolution.

调用microtime（true）函数以获取具有毫秒分辨率的当前时间。

<?php
$startTime = microtime(true);

/*stuff is going on*/

echo "Elapsed time is: ". (microtime(true) - $startTime) ." seconds";

#2

microtime — Return current Unix timestamp with microseconds

microtime - 返回当前的Unix时间戳，以微秒为单位

<?php
$time = microtime(TRUE);

//...code here...

print (microtime(TRUE)-$time). ' seconds';

#3

You could simply use PHP's standard timeout, and implement a shutdown function.

您可以简单地使用PHP的标准超时，并实现关闭功能。

function say_goodbye() {

    if (connection_status() == CONNECTION_TIMEOUT) {
        ... do your special processing to save the process state here
        ... then formulate a response for the browser
    }
}   //  function say_goodbye()


register_shutdown_function("say_goodbye");

Note that you can set the shutdown function to accept parameters

请注意，您可以将关闭功能设置为接受参数

EDIT

编辑

function say_goodbye($controller1,$controller2) {

    if (connection_status() == CONNECTION_TIMEOUT) {
        ... do your special processing to save the process state here
        ... then formulate a response for the browser
    }
}   //  function say_goodbye()


$ctl1 = new DBController();
$ctl2 = new OPController();

register_shutdown_function("say_goodbye",$ctl1,$ctl2);

One of quick and accurate snippet I can recommend.

我可以推荐一个快速准确的代码片段。

//Block of my complex code
//...

echo 'Exact time taken to run: ' . (microtime(true) - $_SERVER['REQUEST_TIME_FLOAT']) . ' seconds';
