Method inheritance and parent classes

I suggest changing the behavior of php to never call methods of classes
that are added by subclasses, only own ones or inherited ones.

Thus rendering the entire Template Method design pattern useless?

I recently had a problem that could be solved, but in an ugly way:
Class B extended Class A. Both classes define a method with the same
name. B called A's constructor, and A called $this->method(). This
executed B::method(), not A::method() as you would expect it.

Most OOP people expect it to run B::method()

That's rather the whole point of inheritence and subclasses.

If you need to override it, you might be able to use A::method()...
Though the OO purists have made that illegal now, I think. :-;

There may be some kind of get_method() function on a class that you
could use like:
$function = get_method('A', 'method');
user_call_func(array($this, $function));

use self::build() or A::build() for that case

Hello all,

I recently had a problem that could be solved, but in an ugly way:
Class B extended Class A. Both classes define a method with the same
name. B called A's constructor, and A called $this->method(). This
executed B::method(), not A::method() as you would expect it.

<?php
class A {
function __construct() {
$this->build();
}

function build() {
    echo "buildA ";
}

}

class B extends A {
function __construct() {
parent::__construct();
$this->build();
}

function build() {
    echo "buildB ";
}

}
new B();
?>

output is: "buildB buildB "
expected would be: "buildA buildB "

I suggest changing the behavior of php to never call methods of classes
that are added by subclasses, only own ones or inherited ones.
