The output of your code is an object not a direct array, use foreach loop and then use array_merge.

Eg. Suppose your output is stored in variable $array

foreach($array as $arrays){
  array_merge('$arrays', $array_you_want_to_merge);
}

Note:- Your code structure is not clear so might be it will not work, but it will will give you an idea.

try this code

$a = $arr[0];
$b = $arr[1];
$newArr= array();
$newArr["items:protected"] = array_merge($a["items:protected"],$b["items:protected"]);

You're using Collections from laravel. While you can use the default PHP functions like array_merge, why not use the laravel way, by using merge.

Copy + pasted from the documentation:

$collection = collect(['product_id' => 1, 'price' => 100]);

$merged = $collection->merge(['price' => 200, 'discount' => false]);

$merged->all();

// ['product_id' => 1, 'price' => 200, 'discount' => false]

OR if you wish to merge 2 collections:

$original = new Collection(['foo']);

$latest = new Collection(['bar']);

$merged = $original->merge($latest); // Contains foo and bar.
