class abstraction (fixed)

[keeB]

Hello everyone, it feels weird posting my own topic instead of answering others! :)

I have a quick question about abstract classes. What is wrong with the following code?

[code=php:0]
<?php
abstract class a {
public $a = 5;
}

class b extends a {
public function b() {
print a::$a;
}
}
?>[/code]

Your thoughts are appreciated

fixed it myself.... apparently $a needs to be declared static in class a :)

fixed code:
[code=php:0]
abstract class a {
public static $a = 5;
}

class b extends a {
public function b() {
print a::$a;
}
}
[/code]
