如何将键值添加到对象中？
我想添加"tags" => ["foo","bar"]到每条记录中，演示：
文章控制器.php
public function index()
{
$articles = user()->articles;
dd($articles); //This is a collection
//loop the collection,and add `"tags" => ["foo","bar"]` into every record
$multiplied = $articles->map(function ($item, $key) {
dd($item);//result below
//how to write here？
});
$newArticles = $multiplied->all();
dd($newArticles);
return view('articles', compact('newArticles'));
}
结果dd($item)：
Article {#498 ▼
#fillable: array:2 [▶]
#casts: array:1 [▶]
#connection: "mysql"
#table: null
#primaryKey: "id"
#keyType: "int"
+incrementing: true
#with: []
#perPage: 15
+exists: true
+wasRecentlyCreated: false
#attributes: array:6 [▼
"id" => 1
"title" => "hello"
"content" => "hello world"
"user_id" => 2
"created_at" => "2017-07-23 15:34:52"
"updated_at" => "2017-07-23 15:34:55"
]
#original: array:6 [▶]
#dates: []
#dateFormat: null
#appends: []
#events: []
#observables: []
#relations: []
#touches: []
+timestamps: true
#hidden: []
#visible: []
#guarded: array:1 [▶]
}
问题： 中
的代码怎么写map()？
$item->tags = ['foo', 'bar'];
return $item;
内部地图将完成这项工作。
但是要映射到 $newArticles。
