Laravel 5.4数组删除键索引

Question

In my controller, this statement generates an array:

// sort the region collection by continent for faster access in front end
$finalRegions = $regions->sortBy('continent_id');


{  
   "0":{  
      "id":1,
      "name":"Alaska",
      "image_x":227,
      "image_y":117
   },
   "1":{  
      "id":5,
      "name":"Australian Antartic Territory",
      "image_x":1187,
      "image_y":1037
....
   }
}

How do I remove the index from the resulting object, so it looks like this:

[  
   {  
      "id":1,
      "name":"Alaska",
      "image_x":227,
      "image_y":117
   },
   {  
      "id":5,
      "name":"Australian Antartic Territory",
      "image_x":1187,
      "image_y":1037
....
   }
]

This is stored in a field cast as json in the table class.

Answer 1

$res = [];
foreach ($finalRegions  as $key => $value) {
    $res[] = $value;
}

// $res contains desired result

Edit: Simple one liner (thanks to Jannie)

$res = array_values($finalRegions)
