給定一個數組，其中每個索引都有某些鍵值對，如何選擇某些鍵值對并拒絕其他鍵值對。$channels = Channel::get()->toArray();這將產生以下數組："channels": [    {        "id": 1,        "name": "Info Release",        "slug": "info-release",        "desc": "Contains blah blah.",        "access_level": "0",        "created_at": "2018-12-02 01:23:50",        "updated_at": "2018-12-05 07:54:41"    },    {        "id": 11,        "name": "Casual News",        "slug": "casual-news",        "desc": "Contains blah blah.",        "access_level": "0",        "created_at": "2018-12-05 05:34:50",        "updated_at": "2018-12-05 07:54:32"    },    {        "id": 12,        "name": "haha",        "slug": "haha",        "desc": "Contains blah blah.",        "access_level": "0",        "created_at": "2018-12-29 23:27:16",        "updated_at": "2018-12-29 23:27:16"    }],將該數組變成這樣的最佳方法是什么："channels": [    {        "id": 1,        "name": "Information Release",        "slug": "information-release",    },    {        "id": 11,        "name": "Casual News",        "slug": "casual-news",    },    {        "id": 12,        "name": "haha",        "slug": "haha",    }],所以如果我寫$channels[0]->id它會吐出來 1
