I was going to propose it when I had more time, but ah well, AUTOLOAD. Basically what this functionality would allow is that you define a function that then catches as missed function calls. The autoload variable would also contain the name of the missing function, ie: class wrapper { function AUTOLOAD() { global $AUTOLOAD; $args = func_get_args(); print "$AUTOLOAD was called with: "; var_dump($args); } } $wrap = new wrapper; $wrap->hello("woohooo!"); would call the AUTOLOAD function with one argument (woohooo!) and the global variable $AUTOLOAD would contain "hello". -Sterling
