Attached is a patch which exports an internals hook in zend_class_entry
for fetching function pointers similar to the object hook get_method()
available to instance methods.
This patch also exports a userspace hook __call_static() which operates
in the fashion of the current __call() magic method, but for static calls.
Wez called for some functionality like this a few weeks ago for a COM
wrapper (or something similar), and I noticed there was actually a
comment in the engine about how this should eventually be done anyway...
Usage example:
class foo
{
public static function __call_static($fname, $args)
{
echo foo::{$fname}() called staticly with ,
count($args), parameters\n;
}
}
foo::randomMethod(1,2,3);
I considered setting get_static_method to zend_std_get_static_method()
by default (avoiding the if set check during runtime), but all the other
hoooks follow this pattern so I went with consistency.
If noone comments to the negative, I'll commit next friday (7/20)...
