Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report

You are calling a method from SubClass out of the BaseClass context.

How about this :

<?php
class BaseClass {
	protected function A($f){
		var_dump($this);
		$this->$f();
	}
}

class SubClass extends BaseClass {
	private function B(){
		echo 'hello, i dont show !';
	}
	public function C(){
		$this->A('B');
	}
}

$b = new SubClass();
$b->C('B');
?>

In this case, i'm calling SubClass:B() from SubClass context. At least, that's how it should work : that's how it works in C, C#, etc...

In PHP 5.2.1 i'm still getting the same fatal error.

The whole point of "private" is that access is only possible from within the class that declares the method (the usual loopholes using reflection and closure rebinding notwithstanding). This is definitely not going to change.

Also [citation needed] on your claim that other languages allow what you suggest, because I'm pretty sure they don't.
