Running python script on background using PHP shell_exec

Question

I have a python script that runs a TCP server and is running indefinitely. This script is working on background in my terminal:

sudo python3 TCPServer.py &

But when I use PHP shell_exec command:

shell_exec('sudo python3 TCPServer.py &')

It executes but waits forever. I want it to run on background.

To run a command in background with shell_exec, the output must be redirected to /dev/null. Refer the php nanual notes.

shell_exec("python3 TCPServer.py 2>&1 | tee -a /tmp/mylog 2>/dev/null >/dev/null &");
