Bug description:Overridden method with same name as child class
Description:
------------
The example below produces a fatal error:
Fatal error: Call to protected b::b() from invalid context in test.php
on line 17
Changing visibility of child's method to public results in b::b() being
invoked twice (prints 'ChildChild').
Renaming the child class to anything but 'b' resolves the issue.
Test script:
---------------
<?php
class a {
protected function b() { echo 'Parent'; }
public function test() {
$this->b();
}
}
class b extends a {
protected function b() { echo 'Child'; }
}
$o = new b();
$o->test();
Expected result:
----------------
The script should print "Child".
Alternatively, if methods with same name as class are not allowed, the
script should fail at parsing stage.
Actual result:
--------------
Fatal error: Call to protected b::b() from invalid context in test.php
on line 17
If b::b() is set public in child, prints 'ChildChild'
