Laravel 5 Collections: Adding New Elements to a Collection With put

The put method is used to add a new item to the collection with a given $key and $value. The put method modifies the original Collection instance and returns a reference to it.

#Signature

1public function put(
2    $key,
3    $value
4);

#Example Use

The following code example highlights the usage of the put method:

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

After the above code has executed, the $collection variable would contain a value similar to the following output:

1object(Illuminate\Support\Collection)
2  protected 'items' =>
3    array
4      'first'  => string 'I am first'
5      'second' => string 'I am second'
6      'third'  => string 'I am third'
