<?PHP
class Testing {

    public function scopeList() {
        echo "scopeList";
    }

    public function __call($method,$parameters) {
        if($method == "list") {
            $this->scopeList();
        }
    }

    public static function __callStatic($method,$parameters) {
        $instance = new static;
        call_user_func_array([$instance,$method],$parameters);
    }
}

//Testing::list();
$testing = new Testing();
$testing->list();

为什么Testing :: list()抛出一个语法错误,而$test-> list()没有？

由于php reserved keywords都应该失败？
