excerpt from php manual:
exec  Execute an external program http://www.php.net/manual/en/function.exec.php
shell_exec  Execute command via shell and return the complete output as a string http://www.php.net/manual/en/function.shell-exec.php
So maybe you can explain what exactly you need to achieve so we can advice the way you should proceed.
Cheers
