Bug description: Automatically translate "self" in method_exists
Description:
------------
In reference to bug #50289:
If I call method_exists("self", "method") from within a class, it
should automatically translate "self" to the classname. Right now the
behavior is not obvious; the behavior does not adhere to the KISS
principle.
1. method_exists already can check for static methods.
2. "self" can already automatically translate to the current class
name, for instance in call_user_func.
3. The most logical, simple and obvious expectation is that if you
combine these two--you call method_exists with "self"--that it will
automatically translate "self" to the current class name, and check
for the method. Currently it does not. The current behavior is
counterintuitive and confusing.
Making this change is not dangerous. Making this change will not cause
any backwards-compatibility issues.
1. "self" is a reserved word. You cannot declare a class named "self"-
-this will issue a fatal error. So there is no possibility of any
ambiguity. You cannot confuse "self" with any other class, because no
other class can be named "self".
It does not make sense to have "self" work in some contexts but not in
others. It would be better if it were consistent.
Reproduce code:
---------------
<?php
class Test
{
public static function check()
{
var_dump(method_exists("self", "method"));
}
public static function method() { }
}
Test::check();
?>
Expected result:
----------------
bool(true)
Actual result:
--------------
bool(false)
