Convert Array To Collection in Laravel

Edit; I understand this question is getting a lot of hits based on the title so the TLDR for those people is to use the collect() helper to create a Collection instance. In answer to the questioner’s brief:

If you have

$collection = collect([
    (object) [
        'website' => 'twitter',
        'url' => 'twitter.com'
    ],
    (object) [
        'website' => 'google',
        'url' => 'google.com'
    ]
]);

You then have your array wrapped in an instance of the Collection class.
That means it does not behave like a typical array (- it will be array-like, but don’t treat it like it is one -) until you call all() or toArray() on it. To remove any added indices you need to use values().

$sorted = $collection->sortBy('website');

$sorted->values()->all();

The expected output:

[
     {#769
       +"website": "google",
       +"url": "google.com",
     },
     {#762
       +"website": "twitter",
       +"url": "twitter.com",
     },
]

See the docs https://laravel.com/docs/5.1/collections#available-methods

The toArray method converts the collection into a plain PHP array. If the collection’s values are Eloquent models, the models will also be converted to arrays.

The all method returns the underlying array represented by the collection.
