can anyone tell me why this doesn't work??
assuming I have these three files:

settings.php is:
<?php $bar="someval"; ?>

page.php is:
<?php   
        require("settings.php"); 
        echo "$bar from page.php"; //this works!!!
        include "function.php";
?>


function.php is:
<?php
        function foo{
        global $bar;
        echo "$bar from foo"; //this does not work!!!
        }
        foo();
?>

for some reason the $bar in function foo() doesn't have a value... :(
calling page.php only returns the $bar from page.php

thanks in advance!
