note 22524 deleted from function.require-once by sniper

Note Submitter: rnakamot@hotmail.com ---- require_once seems to check whether the file is to included by the string that you pass to the function, as opposed to the absolute path of the file. Thus, for example if you have a file at: /home/a.php And executed the following statements from a file in /home/ : require_once("a.php"); require_once("/home/a.php"); a.php would be included twice in that file, potentially causing problems in your code that depend on the file being only included once.
