Question

我有这个对象数组，需要删除键“ 0”：

 "images": [
        {
            "0": "http://example.test/uploads/products/jqGfPyIUc_Wd.jpg"
        },
        {
            "0": "http://example.test/uploads/products/bC1UIM5WwT8f.jpeg"
        }
    ],

我的代码：

'images' => $this->images->map(function($item){ 

      return (object)[$item->image_path];

 }),

我需要删除键并将其保留为这样的数组：

 "images": [
        {
            "http://example.test/uploads/products/jqGfPyIUc_Wd.jpg"
        },
        {
            "http://example.test/uploads/products/bC1UIM5WwT8f.jpeg"
        }
    ],

Answer 1

对象属性应始终具有一个键。如果您不希望它具有键，则应将其存储为嵌套数组：

'images' => $this->images->map(function($item){ 
      return array($item->image_path);
 }),

// will create:

 "images": [
        [
            "http://example.test/uploads/products/jqGfPyIUc_Wd.jpg"
        ],
        [
            "http://example.test/uploads/products/bC1UIM5WwT8f.jpeg"
        ]
    ],

或仅将其映射为字符串值并将其保留为标准数组：

'images' => $this->images->map(function($item){ 
      return $item->image_path;
 }),

// will create:

 "images": [
        "http://example.test/uploads/products/jqGfPyIUc_Wd.jpg",
        "http://example.test/uploads/products/bC1UIM5WwT8f.jpeg"
    ],

Answer 2

尝试这样：

 'images' => $this->images->map(function($item){ 

      return collect((object)[$item->image_path])->values();

 }),

Answer 3

该数组看起来像javascript。如果是这样，则可以将其映射如下。

viewbox

如果它是一个php数组，则它似乎来自console.log(images); /* [ {'0': 'http://example.test/uploads/products/jqGfPyIUc_Wd.jpg'}, {'0': 'http://example.test/uploads/products/bC1UIM5WwT8f.jpeg'} ] */ console.log(images.map(value => value[0])); /* [ 'http://example.test/uploads/products/jqGfPyIUc_Wd.jpg', 'http://example.test/uploads/products/bC1UIM5WwT8f.jpeg' ] */调用。您可以json_decode。

map
