What function am I in?

[Anon]

Hello everyone. Took a quick look, and couldn't find anything, so here goes (and please forgive me if this has been addressed - just point me in the right direction!):

Okay. We have a large application, many include files, tons of functions, etc. One of these functions is breaking my session. I need to find out which. So, I have written a function that simply logs the filename it's being run from, as well as the contents of session variables. Let's call this function SESSION_KILLER. Now, I want to run SESSION_KILLER from within every function, to find my culprit. I would ideally like to log the function that called SESSION_KILLER. Is there a way to do this?

Thanks a million,

Just have this at the top of your first file:

<?php

$fp = fopen('sessions.log', 'w');

function session_killer($file, $line) {
global $fp;
fputs($fp, "Last Called from: $file on line $line\n");
}

?>

In each function you call, insert:

session_killer(FILE, LINE);

(Yes the FILE and LINE are php keywords).
