PHP version: 5.2.3
PHP Bug Type: Reproducible crash
Bug description: false positive on input error checking
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)"
