Determine in which file a user function is defined?

Aug 7th, 2007

Hello,

I am familiar with the get_defined_functions() function as a way of listing all of the user defined functions.

Is there a way with PHP to also determine from which file the user function was defined?

Consider the following example. Assume there are three files:
- index.php
- user_functions1.inc.php
- user_functions2.inc.php

contents of user_functions1.inc.php:

<?php
function example_function1() {
    print "hello world 1";
}
?>

contents of user_functions2.inc.php:

<?php
function example_function2() {
    print "hello world 2";
}
?>

contents of index.php:

<?php
include(user_functions1.inc.php);
include(user_functions2.inc.php);
$functions = get_defined_functions();
$user_functions = $functions['user'];
foreach($user_functions as $function) {
	print "$function<br>";
}
?>

output of index.php:

example_function1
example_function2

I would like to use PHP to determine that user function example_function1 was defined in the file user_functions1.inc.php

Is this possible?

Thank you.
