老问题的新答案。使用这个库，下面的代码将生成一个异步/并行PHPThread来执行后台工作。

必须有pcntl, posix和套接字扩展名 在CLI模式下设计/测试。

EZ代码示例:

 function threadproc($thread, $param) {
 
    echo "\tI'm a PHPThread.  In this example, I was given only one parameter: \"". print_r($param, true) ."\" to work with, but I can accept as many as you'd like!\n";
 
    for ($i = 0; $i < 10; $i++) {
        usleep(1000000);
        echo "\tPHPThread working, very busy...\n";
    }
 
    return "I'm a return value!";
}
 

$thread_id = phpthread_create($thread, array(), "threadproc", null, array("123456"));
 
echo "I'm the main thread doing very important work!\n";
 
for ($n = 0; $n < 5; $n++) {
    usleep(1000000);
    echo "Main thread...working!\n";
}
 
echo "\nMain thread done working.  Waiting on our PHPThread...\n";
 
phpthread_join($thread_id, $retval);
 
echo "\n\nOur PHPThread returned: " . print_r($retval, true) . "!\n";

如果使用PHP，使用pcntl_fork有一个更简单的方法:

我知道这是一个有100年历史的帖子，但不管怎样，我觉得它可能对某人有用。你可以在页面的某个地方放一个不可见的图像，指向需要在后台运行的url，就像这样:

<img src="run-in-background.php" border="0" alt="" width="1" height="1" />

我大量使用fast_cgi_finish_request()

结合使用闭包和register_shutdown_function()

$message ='job executed';
$backgroundJob = function() use ($message) {
     //do some work here
    echo $message;
}

然后注册这个闭包，在关闭之前执行。

register_shutdown_function($backgroundJob);

最后，当响应被发送到客户端时，您可以关闭到客户端的连接，并继续使用PHP进程:

fast_cgi_finish_request();

闭包将在fast_cgi_finish_request之后执行。

$消息在任何时候都不可见。您可以注册任意数量的闭包，但要注意脚本执行时间。 这将只在PHP作为一个快速CGI模块运行时工作(这是正确的吗?!)

与其启动后台进程，不如创建一个触发器文件，并让像cron或autosys这样的调度程序定期执行一个寻找触发器文件并对其进行操作的脚本?触发器可以包含指令甚至原始命令(更好的方法是将其变成shell脚本)。
