one of the solutions is:

Code:
<?php
exec("comand & sleep 3 ; kill $!");
?>

Gently

Seems reasonable to me, but I'd do this:
Code:
exec("comand && (sleep 3 ; kill -TERM $!; sleep 1; kill -9 $!)");

This mimics the usual shutdown sequence: give the process a change to die gracefully (-TERM) but if it hangs, terminate with extreme prejudice (-9).
