php 抽象类和__callStatic()

abstract class xyz{//抽象类


    public static function __callStatic($method, $args)//在静态上下文中调用一个不可访问方法时，__callStatic() 会被调用。
    {
        echo "Calling static method '$method' "
            . implode(', ', $args). "\n";

        echo def::$method($args);
    }
}

class def extends  xyz{

    public function boot1(){
        echo 'def';
    }
}
def::boot1('in static context');exit;

class abc {


    public  function test(){
        def::boot1();
    }

    protected static function boot()
    {
        echo 'abc22231';
    }
}




$abc = new abc();
echo $abc->test();exit;
