How to update a nested value within a nested Laravel collection

Question

I have a deployments Laravel Collection like this:

Illuminate\Support\Collection {#415 ▼
  #items: array:5 [▼
    0 => array:7 [▼
      "id" => 31
      "status" => "active"
      "name" => "Deployment 1"
      "spots" => array:4 [▼
        0 => array:2 [▼
          "id" => 33
          "status" => "active"            <-- Want to change this
        ]
        1 => array:2 [▶]
        2 => array:2 [▶]
        3 => array:2 [▶]
      ]
      "data" => array:3 [▶]
    ]
    1 => array:7 [▶]
    2 => array:7 [▶]
    3 => array:7 [▶]
    4 => array:7 [▶]
  ]
}

I want to update the nested status value to inactive. I have used the Laravel map function, but it only seems to work on collections that have one nesting level. So this...

$this->deployments->map(function ($deployment) {
    $deployment['spots'][0]['status'] = 'inactive';
});
dd($this->deployments);

...leaves $this->deployments untouched.

Also tried using nested map functions obtaining a Call to a member function map() on array exception on second level as second and next nesting levels are considered arrays...

Any thoughts? Thanks in advance.

With the map method, you are almost there. You will have to return the change made in $deployment and do an ->all() at the end to update the collection with the modified values.

For updating a single spot:

$deployments = $deployments->map(function($deployment){
    $deployment['spots'][0]['status'] = 'inactive';
    return $deployment;
  })->all();

For updating all spots:

$deployments = $deployments->map(function($deployment){
    foreach($deployment['spots'] as &$spot){
      $spot['status'] = 'inactive';
    }
    return $deployment;
  })->all();
