I have an array as follows

```
$user_followers = [
    [
        'user_id'   => '1',
        'followers' => ['3', '4', '5']
    ],
    [
        'user_id'   => '2',
        'followers' => ['1', '5']
    ],
    [
        'user_id'   => '3',
        'followers' => ['1', '5', '4']
    ],
    [
        'user_id'   => '4',
        'followers' => ['3', '1', '5']
    ],
    [
        'user_id'   => '5',
        'followers' => ['1', '2', '4']
    ],
];

```

What I need to do is obtain the followers data array based on the user\_id value therefore if I have a `user_id` of 2 it will return an array containing the `followers` array data. I am not sure whether I need to re organise my array structure to do this.
