I' am calling sell script from my php code with 

foreach ($some_array) {
     shell_exec(nohup $code); 
}

like above

I want all shell_exec call to work independent from mail process which is php execution that we call shell script

But It's not working as I expected all shell_executions start right after previous one completed

So how can I make this shell_exec calls as independent child process that they don't wait each others completation

Thanks in advance

Add the '&' to the end of the command you want to execute so it works in background.

For a sequence of commands, enclose them within parentheses then append the & symbol but be sure to redirect stdout, stderr somewhere otherwise your script will hang waiting e.g.:

<?php

exec('( sleep 10; echo "finished" | mail ian@example.com ) &> /dev/null &');

?>

See http://us.php.net/manual/en/function.exec.php

Send them to the background

shell_exec("nohup somecommand &");
                              ^---run job in background

  • Doesn't work, at least in PHP 5.5. Try saving this simple script as `test.php` and running it: ``. You'll see a growing list of PHP processes in `ps -e`. – Mark Amery Aug 11 '14 at 15:47
