Description:
------------
I define a function that asks for a string with default set to null, then call it with non-null input, resulting in a PHP Catchable fatal error.

Reproduce code:
---------------
<?php
class output {
	public static function echo_params($p1 = "Hello World", string $p2 = null, bool $p3 = null) {
		// code that echoes the non-null parameters in a list
	}
}
echo output::func(null, "Hello World");
?>

Expected result:
----------------
p2 = Hello World

Actual result:
--------------
[Mon Aug 27 17:02:41 2007] [error] [client 127.0.0.1] PHP Catchable fatal error:  Argument 2 passed to output::echo_params() must be an instance of string, string given, called in F:\\Services\\Apache2\\htdocs\\index.php on line 8 and defined in F:\\Services\\Apache2\\htdocs\\index.php on line 4


(as a side note, really wanted): full, clean method overloading allowing declarations like "func(string a, string b)" alongside "func(string a, bool x, bool y)" and "func(string a, int z)"
