<?php
function term() {
if(function_exists('apache_child_terminate')) {
apache_child_terminate();
}
die('Terminated');
}
?>
Also, when apache_child_terminate is called, it terminates the script, so die()/exit() is not necessary if the script is 100% sure to be on an apache 1.x server, else a die()/exit() is as good as it gets.
I found its a semi-good idea to terminate the child if available after critical low-level errors.
