execute bash script from php without waiting

Question

I execute a bash script from php with shell_exec. But the php script waits until the shell script is finished.

Can I somehow call the bash script without waiting. Both:

exec
shell_exec

are waiting until the bash script is finished. I'm running linux btw.

This has to work:

exec('/your/command /dev/null 2>/dev/null &');

when calling your bash script append & so it will run in the background that's the easiest way if you don't need any output

shell_exec("/bin/bash /path/to/script.sh &");

what exactly did not work? the running in the background? the script? maybe it is a permission problem

php was still waiting until the script was executed. "sh command > /dev/null 2>&1 &" did the trick though. thanks for your help :)
