Fastest way to determine where PHP script exits

php

Solution

With some inspiration from the nonworking but still right-direction answer from RoBorg, I used the following code in the beginning:

function shutdown() {
    global $dbg_stack_a;
    print_r($dbg_stack_a);
}
register_shutdown_function('shutdown');

And then I made a global conditional breakpoint (global = breakpoint is evaluated on each row), exploiting the fact that it can run code trough eval(), with the following "condition":

eval('
global $dbg_stack_a, $dbg_stack_b, $dbg_stack_c;
$dbg_stack_a = $dbg_stack_b;
$dbg_stack_b = $dbg_stack_c;
$dbg_stack_c = debug_backtrace();
return false;
')

Probably not fast but does the trick! Using this I was able to determine the exact file and line location that raised die(). (This example works in NuSphere.)

Problem

Say you have a large PHP project and suddenly, when attempting to run it, you just end up with a blank page. The script terminates and you want to find exactly where that is with as little effort as possible. Is there a tool/program/command/IDE that can, on PHP script termination, tell you the location of a script exit? Note: I can't mark my own post as "accepted answer" so look at the bottom to see my solution. If you come up with a better solution I will mark your post as the answer.
