我们不仅仅可以向视图传送一个数据,同样我们可以传送Array

代码如下:


    public function about()
    {
        return view('pages.about')->with([
            'first' => 'Zhang',
            'last' => 'Jinglin'
        ]);
    }

About {{ $first }} {{ $last }}


一种简洁的方式是这样:

代码如下:


    public function about()
    {
        $data = [];
        $data['first'] = 'Zhang';
        $data['last'] = 'Jinglin';
        return view('pages.about', $data);
    }

结果相同,更简单的是这样:

代码如下:


    public function about()
    {
        $first = 'Zhang';
        $last = 'Jinglin';
        return view('pages.about', compact('first', 'last'));
    }

compact 把参数变成数组,extract相反。可以查看php手册了解 compact ,顺道了解一下 extract。
