Laravel 5 Collections: Retrieving Collection Elements With get

The get method can be used to retrieve an item from the collection based of its $key. An optional $default argument can be passed that will be returned if the supplied $key does not exists in the collection. The $default argument can be a simple value, or a callback that will be evaluated and the return value returned from the get method.

#Signature

1public function get(
2    $key,
3    $default = null
4);

#Example Use

The following code sample demonstrates the use of the get method:

 1use Illuminate\Support\Collection;
 2 
 3// Create a new collection instance.
 4$collection = new Collection([
 5    'first'  => 'I am first',
 6    'second' => 'I am second'
 7]);
 8 
 9// I am second
10$second = $collection->get('second');

By default, the get method will return null if a $key does not exist within the collection. However, a different value can be supplied, as well as a callback:

 1// null
 2$value = $collection->get('third');
 3 
 4// default
 5$value = $collection->get('third', 'default');
 6 
 7// default
 8$value = $collection->get('third', function() {
 9    return 'default';
10});

The get method can also retrieve items based on numeric keys:

 1use Illuminate\Support\Collection;
 2 
 3// Create a new collection instance.
 4$collection = new Collection([
 5    'first',
 6    'second',
 7    'third'
 8]);
 9 
10// first
11$value = $collection->get(0);
