ass & at the end of the command.

$D_command="nohup rm -rf videos/'$Mdelete' > /log/deletedfile.log 2>&1 &";

$PID = shell_exec("nohup $Command 2> /dev/null & echo $!");

Try running

rm -rf videos/'$Mdelete' &

using exec. The ampersand indicates to run to the background

Try this:

popen($D_command, 'r')

I know this is quite an old question, but I had the same issue, and this was the only working solution after trying and failing with exec,shell_exec, process_open:

$process = popen("nohup $D_command > /dev/null 2> /dev/null & echo $!", 'r');
$pid = fread($process, 32);
