i try to run php processes in background and start this from an php file.
Some informations: PHP Version 5.2.17, php safe_mode is off, linux system. I start the process with exec, tried already shell_exec. I set all files to 0755, 0777.
$pid = exec("nohup $cmd > /dev/null 2> /dev/null & echo $!");
If i print this statement, i get this and the pid is okay:
nohup /usr/local/bin/php5 /.../../file.php > /dev/null 2> /dev/null & echo $!
If i look for processes under ssh with
top
i see my php5 process with the correct pid. user is root
