push($value)

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 following code example shows how to use the push method to put an item on the end of the collection:

 1<?php
 2 
 3use Illuminate\Support\Collection;
 4 
 5// Create a new collection instance.
 6$collection = new Collection([
 7    'I am first',
 8    'I am second'
 9]);
10 
11// Push an item onto the collection.
12$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)[133]
2  protected 'items' =>
3    array (size=3)
4      0 => string 'I am first' (length=10)
5      1 => string 'I am second' (length=11)
6      2 => string 'I am third' (length=10)

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.
