I can echo the variables from my require_once file outside of a function, but inside a function they are empty (i.e. it's as if they were never parsed by require_once at all). Even adding a seperate require_once in the function will still echo empty variables.

Got it : I should declare the variables I need from the require, with 'global' in the function. ref : http://us2.php.net/manual/en/languag...bles.scope.php.
