weird include error

[jasondavis]

Below is a smaple of my page, it has about 3,000 lines of code for my functions and this file is included into every page, what I am trying to do is break this page into smaller files so it is easiar to manage the code, for example I made a forum.inc.php file to put all the forum functions in and then I remove that code from this main file and try to include the new file into this file, it seems to include it, because if I do not remove the current forum functions it will say I can not redeclare the function, however anytime I try to include one of these files it makes the screen output blank, I cant seem to figure out what could be causing this

<?
session_start();
require_once "config.inc.php";

//include "functions/sanitize.inc.php";
//include "functions/notifications.inc.php";
//include "functions/photo.inc.php";
//include "functions/group.inc.php";
//include "functions/forum.inc.php";
//include "functions/classifieds.inc.php";
//include "functions/accountsettings.inc.php";

//Kills all dangerous user inputed code
function FilterHTML($string) {
	if (get_magic_quotes_gpc()) {
		$string = stripslashes($string);
	}
//rest of functions code...................................
)
?>

Do you have error_reporting set to E_ALL and display_errors set to on?

[jasondavis]

yes both are set but still ouptuts nothing, it strange

Well, I cannot see anything particularly wrong with your code, though using <?php instead of <? would be preferred. Post the smallest and simplest code that demonstrates the problem.

Are you positive there was no output (e.g. did you view the source of the page)? A "blank" white page is certainly no guarantee that there was no output.
