Call by reference to function arguments

Hi, I want to write a function (as I have written in several other languages) that obtains it's arguments dynamically (using func_get_arg()) and then assigns to that argument. Think of the way that scanf() works -- that sort of thing. I have distilled what I want to do in the code below. foo adds 1 to all of it's arguments. function foo () { $count = func_num_args(); for($i = 0; $i <= $count; $i++) { $var = func_get_arg($i); // The following line should do it, but throws a syntax error &$var = $var + 1; } } $a = '1'; $b = '2'; $c = '3'; foo($a, $b, $c); What I am doing is quite different than the above (and more complex), but I will be able to achieve what I want if I can get the above to work. -- Alain Williams #include <std_disclaimer.h>
