static call to an instance method in a class definition

Hello,
Making a mistake I just come to discover ( for myself ) a strange fiture in
php,
lets see an example :

class A{

public $foo =3D 'bar';

public function write(){

print($this->foo);

}

}


class B{

public $foo =3D 'gnagnagna';



public function write(){

A::write();

}

}


$var =3D new B;

$var->write();


This code will not throw excaption and output gnagnagna, it's kind of cross
définition something,
I know something like that exists in other language but I didn't expect PHP
to work like that.

Do you know this ? And why ?

Re: static call to an instance method in a class definition

Hi.

I knew about this "feature" ($this is used from the caller scope if
the called method is static), but I didn't checked the manual about
this.
Now I did it.

http://php.net/manual/en/language.oop5.static.php
"Because static methods are callable without an instance of the object
created, the pseudo-variable $this is not available inside the method
declared as static."

some comments point out this behaviour, but either the code, or the
documentation is wrong.
