Description:
------------
i'm writing code that invokes "hooks" with byref parameters.
but the generalized hook functions lose the byref information due to func_get_args being a copy (but
not exact), thus call_user_func_array() (which needs to have references in it's array)
can't work.
see shortened example below:
Test script:
---------------
$foo = "foo";
$bar = "bar";
function func_a(&$a, $b) {
$a = $b;
};
function c() {
$args = func_get_args();
call_user_func_array("func_a", $args);
};
c(&$foo, $bar);
var_dump($foo);
Expected result:
----------------
i expected for $foo to have 'bar'
Actual result:
--------------
$foo is still 'foo', and a warning is generated
