¿Las clases extendidas heredan los valores de VAR STATIC (PHP)?

Question

Si tengo una clase base que contiene un VAR estático, configuro este VAR estático y luego tendrá una clase que extienda la clase base, la clase extendida conservará el valor de la var static que ya he establecidola clase base?

Answer 1

Yes, although they're different variables, the static variables in both classes are in the same reference set.

You can break this reference set though, by using reference assignment (=&) or by redeclaring it in the extended class:

class base {
    public static $var;
}
class extended extends base {}

extended::$var = 8; // base::$var == 8
$t = 6;
extended::$var =& $t; // base::$var == 8; extended::$var == 6

class base {
    public static $var;
}
class extended extends base {
    public static $var;
}

extended::$var = 8; // base::$var == null; extended::$var == 8
