The push method is the logical opposite of the prepend method and will push an item onto the end of the collection. The push method returns a reference to the original collection instance.

The push method modifies the collection instance it was invoked on.

#Signature

1public function push(
2    $value
3);

#Example Use

The following code example demonstrates how to use the push method to add an item on the end of a collection:

 1use Illuminate\Support\Collection;
 2 
 3// Create a new collection instance.
 4$collection = new Collection([
 5    'I am first',
 6    'I am second'
 7]);
 8 
 9// Push an item onto the collection.
10$collection->push('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      0 => string 'I am first'
5      1 => string 'I am second'
6      2 => string 'I am third'

It should be noted that the push method cannot be used to set the key of the item that is being added to the collection.
