数组的多维关联数组

为什么这不会推迟或添加到最后？

这两种方法我都试过了。

class Router
{
    public function __construct()
    {
        $this->routes['GET'] = [];
        $this->routes['POST'] = [];
    }

    public function handle($request)
    {
        echo count($this->routes['GET']) . "<br/>";  // outputs '0'.. why??
    }

    protected function addRoute($methods, $uri, $action)
    {
        #array_push($this->routes['GET'], 'TEST'); // Tried this as well
        $this->routes['GET'][] = 'test';
        echo count($this->routes['GET']) . "<br/>";  // outputs '1'
    }

    private $routes = [];
}

在我执行addRoute然后检查$this->routes[$methods]using count()in的大小后handle($request)，它显示为 0。
