Exactly what I wanted to s= ay for this topic. Have a look at this example that could be very similar i= n production code in some systems:
<?php

interface= A {
public static function run();
public = static function stop();}

abstract class B imp= lements A {
public static function run() {
static::c= reate();
static::start(); }
}

class C exte= nds B {
public static function create() {
echo "Create\n";
}

= public static function start() {
echo "Start\n";
}=

public static function stop() {
echo = "Stop\n";
}
}

function e= xecute($class) {
if (!is_subclass_of($class, A::class)) {
thr= ow new RuntimeException("Class must implement A interface"= ;);
}

$clas= s::run(= );
$class::stop();
};
execute<= span style=3D"font-family:"JetBrains Mono",monospace;color:rgb(8,= 8,8)">(C::class)= ;

If we support inheritance for stat= ic classes, we should allow static on both interface and abstract classes.<= br>
