how to convert an array to a collection in Laravel?

To convert an array to a collection in Laravel, you can use the collect helper function. This function will create a new Illuminate\Support\Collection instance from the given array.

Here’s an example:

$array = [1, 2, 3, 4];
$collection = collect($array);

// $collection is now a collection object containing [1, 2, 3, 4]

You can also pass a multidimensional array to the collect function, and it will recursively convert the nested arrays to collections as well:

$array = [[1, 2], [3, 4], [5, 6]];
$collection = collect($array);

// $collection is now a collection object containing [[1, 2], [3, 4], [5, 6]]

The collect function is a convenient way to create a collection from an array, especially if you need to work with the array items using the methods of the Illuminate\Support\Collection class.

If you have an object that implements the Traversable interface, you can also pass it to the collect function and it will be converted to a collection.

$object = new ArrayObject([1, 2, 3, 4]);
$collection = collect($object);

// $collection is now a collection object containing [1, 2, 3, 4]
