Answer 1

Can you try one of the following 2 commands to run background jobs from PHP:

$out = shell_exec('nohup /usr/bin/php /path/to/gutschein.php >/dev/null 2>&1 &');

OR

$pid = pclose(popen('/usr/bin/php gutschein.php', 'r'));

It will execute the command in background and returns you the PID, which you can check using condition $pid > 0 to ensure it has worked.
