PHP tells you that you're accessing an index of an array that is not defined ($perm['userPermission']). PHP tells you this because it may be a logical error within your application - but here it isn't. You may safely (here ;->) turn notifications off either by editing php.ini, or by adding the line error_reporting(E_ALL & ^E_NOTICE); to your script to remove such notifications. From PHP.INI: ; error_reporting is a bit-field. Or each number up to get desired error ; reporting level ; E_ALL - All errors and warnings ; E_ERROR - fatal run-time errors ; E_WARNING - run-time warnings (non-fatal errors) ; E_PARSE - compile-time parse errors ; E_NOTICE - run-time notices (these are warnings which often result ; from a bug in your code, but it's possible that it was ; intentional (e.g., using an uninitialized variable and ; relying on the fact it's automatically initialized to an ; empty string) ; E_CORE_ERROR - fatal errors that occur during PHP's initial startup ; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's ; initial startup ; E_COMPILE_ERROR - fatal compile-time errors ; E_COMPILE_WARNING - compile-time warnings (non-fatal errors) ; E_USER_ERROR - user-generated error message ; E_USER_WARNING - user-generated warning message ; E_USER_NOTICE - user-generated notice message A valid configuration where only runtime fatal errors are reported would be error_reporting(E_ERROR); Better use error_reporting(E_ALL & ^(E_NOTICE | E_WARNING)); -- >O Ernest E.
