include/require- redecare function
hi, my problem sounds like this..
i have a page, s.php, works well. in s.php, i have to include header.php and 1.php.
in my header.php, i already include 1.php. so when i include header.php in 1.php, i got error...says...cannot redeclare...a function. so i thought i dun need to include 1.php in my s.php and it should works. but it didn't.
what should i do? i tried using include_once and require_once but the error is still there. pls help..

you can try something like this:
in header.php define a constant like:
<?phpdefine('HEADER_ALREADY_INCLUDED',1);
?>
in 1.php, test to see if the header is already included:
<?phpif(!defined('HEADER_ALREADY_INCLUDED')) require 'header.php';
?>

well, actually my problem is with the file i include in header.php.
u see,
i have 2 page, header.php and 1.php, both need to include function.php inorder to run correctly.
my problem is, in header..i include function..every single page i also haveto include header. and i thought ih ave the function included in header, i dun need to include it in my 1.php, but i'm wrong. my 1.php didn't run well. therefore, i have to include both function in both header and 1.php

I think it's time for example urls... (and .phps files).
If you include function.php in header.php and header.php is always included in every page, you shouldn't have to do it twice.

in functions.php...
<?php
if(!defined(FUNCTIONS_ALREADY_INCLUDED')) {
define (FUNCTIONS_ALREADY_INCLUDED', TRUE);
// contents of file
} //END define
?>

Can someone explain (in simple terms) why you'd need to include a file that's already included on every page? Please? I'm quite confused now.

When you modularize a program, each of your modules will include their dependencies. Sometimes more than one module requires the same dependency... then you need a mechanism to catch this.

assuming these modules work in other combinations to do different things or in different circumstances, then? gotcha.
