php-在雄辩的Laravel集合的每个元素的开头添加一个项目

我有这样的收藏

[
  {
    "objective_id": "26",
    "objective_weight": "50.00",
    "objective_description": "This is first strategic objective",
    "actions": [
    ]
  },
  {
    "objective_id": "27",
    "objective_weight": "12.00",
    "objective_description": "This second strategic objective",
    "actions": [
    ]
  },

]

现在,我想为集合的每个元素添加一个项目.例如：

[
  {
    "foo" : "bar"
    "objective_id": "26",
    "objective_weight": "50.00",
    "objective_description": "This is first strategic objective",
    "actions": [
    ...
    .....

我已经尝试了Eloquent的prepend()方法,但是没有成功.

$new = $objectives->map(function($objective) {
    return $objective->get()->prepend('hello', 'world');
});

return $new;

解决方法:

这些项目只是对象,您可以通过设置属性来添加属性：

$new = $objectives->map(function($objective){
    $objective->foo = 'bar';
    return $objective;
});
