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

public function push(
    $value
);

Example Use

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

use Illuminate\Support\Collection;

// Create a new collection instance.
$collection = new Collection([
    'I am first',
    'I am second'
]);

// Push an item onto the collection.
$collection->push('I am third');

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

object(Illuminate\Support\Collection)
  protected 'items' => 
    array
      0 => string 'I am first'
      1 => string 'I am second'
      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.
