如何停止一个PHP脚本在后台运行 [英] How do I stop a PHP script running on the background

问题描述

我开始了这一进程（time.php）

I started this process (time.php)

<?php

ignore_user_abort(true); // run script in background
set_time_limit(0);       // run script forever 
$interval = 300;         // do every 1 minute...
do
{ 
    // add the script that has to be ran every 1 minute here
    // ...

    $to      = "[e-mail]";
    $subject = "Hello Richie";
    $header  = "From: [e-mail]";
    $body    = "Hello Richard,\n\n"
             . "I was just testing this service\n\n "
             . "Thanks! ";

    mail($to, $subject, $body, $header);

    sleep($interval); // wait 5 minutes

} while(true); 
?>

但我现在想停止它。它让数百名邮件到我的Gmail的A / C。这就是我不能重新启动它杀死进程的Web服务器上。

but I now want to stop it. It's sending hundreds of mail to my Gmail a/c. It's on a web server where I cant restart it to kill the process.

有没有执行其他文件杀死进程的一种方式，或者我怎么去？

Is there a way to execute another file to kill the process, or how do I go about?

推荐答案

如果你没有shell访问，那么唯一的办法就是要求服务器administrater杀死进程。

If you don't have shell access, then the only way is to ask the server administrater to kill the process.

话虽这么说，没有建立一个脚本，使它能够在同一台服务器上的任何其他脚本被取消的简单方法如下：

That being said, there is an easy way to set up a script and enable it to be canceled from any other script on the same server, as follows:

<?php
// at start of script, create a cancelation file

file_put_contents('/tmp/myscriptcancelfile','run');

// inside the script loop, for each iteration, check the file

if ( file_get_contents('/tmp/myscriptcancelfile') != 'run' ) { 
    exit('Script was canceled') ; 
}

// from any other script on the same server you can cancel the loop/exit with:

file_put_contents('/tmp/myscriptcancelfile','stop');
?>
