PHP include 'function' problem

[LonLonRanch]

I'm currently working on a script where I use an include (); statement to add a php file that contains all my funcitons. I have another include file in the same page that loads data that makes reference to one of the funcitons, however everytime I run the script I get this message:

Fatal error: Call to undefined function write_log() in /home/mysite/www/www/example/example.php on line 37

Which means the function is undefined, even though it should be defined from the include(); statement
I have tried this page without using any include(); statements and it works fine so I'm wondering if there is something I need to be doing to my functions (is there a global function() statement or something?) Can anyone help me out?

As long as you include the function on whatever page your using it should work.

<?
//functions.php
function MyFunc(){
echo "MyFunc!";
} ?>
<? 
//index.php
include("functions.php");
MyFunc();
?>

That will display "MyFunc!" on index.php

Hmm strangely enough changing my syntax from:

include ("file.php");
include 'file.php';

seemed to have fixed the problem, odd...
