What about using normal pass-by-value and returning the result? function MyFunc ($SomeVal) { $SomeVal += 42; return $SomeVal; } echo MyFunc ($StrangeVal); Anyway - functions that get their parameters by reference and modify them can cause much trouble, so better be careful with that. -- Christian Reiniger LGDC Webmaster (http://sunsite.dk/lgdc/) I saw God --------- and she was black.
