Class inheritance in PHP 5.2: Overriding static variable in extension class?
- by Christoffer
Hi,
I need to bea be able to use a static variable set in a class that extends a base class... from the base class.
Consider this:
class Animal {
public static $color = 'black';
public static function get_color()
{
return self::$color;
}
}
class Dog {
public static $color = 'brown';
}
echo Animal::get_color(); // prints 'black'
echo Dog::get_color(); // also prints 'black'
This works wonderfully in PHP 5.3.x (Dog::get_color() prints 'brown') since it has late static binding. But my production server runs PHP 5.2.11 and so I need to adapt my script.
Is there a somewhat pretty workaround to solve this issue?
Cheers!
Christoffer
