Note Submitter: Jonathan (jojonaloha at gmail dot com) ---- In response to Jarobman What you are experiencing isn't a bug, but it is an error. Those unquoted strings are being interpreted as undefined constants. From the documentation: If you use an undefined constant, PHP assumes that you mean the name of the constant itself, just as if you called it as a string (CONSTANT vs "CONSTANT"). An error of level E_NOTICE will be issued when this happens. See also the manual entry on why $foo[bar] is wrong (unless you first define() bar as a constant). If you simply want to check if a constant is set, use the defined() function. http://us2.php.net/manual/en/language.constants.syntax.php Hope that helps!
