Can you unregister a shutdown function?

Question

Is it possible in PHP to unregister a function (or all functions) set up with register_shutdown_function()?

Answer 1

Hi I made a slight modification to the way my function worked as follows:

function onDie(){
    global $global_shutdown;

    if($global_shutdown){
        //do shut down
    }
}

$global_shutdown = true;
register_shutdown_function('onDie'); 

//do code stuff until function no longer needed.

$global_shutdown = false;
