Laravel 5: Randomizing Element Order With shuffle

The shuffle method can be used to shuffle an input array and then returns the results. This method takes advantage of PHP's shuffle method; therefore, it is not suitable for cryptographic purposes.

#Signature

The signature of the shuffle method is:

1public static function shuffle(
2    $array
3);

#Example Use

In the crossJoin section we looked at how to quickly create a deck of cards using the crossJoin method. Let's bring that back and use the shuffle method to shuffle our deck of cards:

 1use Illuminate\Support\Arr;
 2
 3// Create our deck of cards.
 4$suites    = ['Clubs', 'Diamonds', 'Hearts', 'Spades'];
 5$cardValues = ['A', 2, 3, 4, 5, 6, 7, 8, 9, 10, 'J', 'Q', 'K'];
 6
 7$deckOfCards = Arr::crossJoin($suites, $cardValues);
 8
 9// Shuffle our deck of cards.
10$shuffledDeck = Arr::shuffle($deckOfCards);
