There was a specific reason that the require to the file defining the
function came after the call to the function. But alas, it doesn't
matter what the reason is now.
Thanks for the explanation.

Files are included/required at run-time. As such, the function has not
been declared when you make reference to it since the require occurs
later. Move the require to the top. As a test, feel free to explicitly
define the function at the bottom without using a require.
Cheers,

Hello,
According to the PHP manual on functions (http://www.php.net/manual/
en/language.functions.php):
"In PHP 3, functions must be defined before they are referenced. No
such requirement exists since PHP 4. Except when a function is
conditionally defined..."
If that is true then why does the following not work as I expect?
I expect the result to be "Function was called!" but it actually is
"Function test() does not exist!".
File: a.php
<?php
if (function_exists('test')) {
echo test();
}
else {
echo "Function test() does not exist!";
}
require 'b.php';
?>
-------------------------------
File: b.php
<?php
require 'c.php';
?>
-------------------------------
File: c.php
<?php
function test() {
return "Function was called!";
}
?>
