[英]Run Python script from php, save process pid, and don't wait it to finish
I have a PHP script that runs a python script with shell_exec('myScript.py'). 我有一个PHP脚本,该脚本使用shell_exec('myScript.py')运行python脚本。 It works nicely, but I don't want to wait that python script to finish.
它工作得很好,但我不想等待该python脚本完成。 Also I need to know that process pID so I can stop it if I want.
另外,我需要知道该进程的pID,以便在需要时可以将其停止。 How can I do both things?
我该怎么办? I know that adding "& $!"
我知道添加“&$!”。 in the terminal after "myScript.py" gives me the pID, and that I can kill that process with: "kill -SIGTERM pID", but only from terminal.
在终端“ myScript.py”之后给我pID,然后我可以使用“ kill -SIGTERM pID”杀死该进程,但只能从终端执行。 Thanks in advance.
提前致谢。
In more detail, this is what i want to achieve: I got a raspberry pi. 更详细地说,这就是我要实现的目标:我得到了一个树莓派。 That raspberry pi can control stuff with python scripts (lights, sockets...).
那个树莓派可以用python脚本(灯光,套接字...)来控制东西。 Also, i got a home webserver installed in that raspberry pi.
另外,我在该树莓派中安装了一个家庭网络服务器。 The objective is having a webpage, and being able to run and stop that python scripts from it.
目的是拥有一个网页,并能够从中运行和停止该python脚本。
you gotta put some bash magic into it. 您必须在其中添加一些bash魔术。
$a = exec('python myScript.py > /dev/null 2>&1 & echo $!');
echo $a;
