As far as i know, if you try to require the SAME file several times, it just includes it one time... not as include: require "file.php"; require "file.php"; require "file.php"; require "file.php"; require "file.php"; require "file.php"; would do the same as include "file.php"; Require SHOULD (computers sometimes just don't obbey you) ignore the second, thinrd and so on calls.
