How to add elements to a collection in illuminate/collections?

To add elements to a collection in Illuminate/Collections, you can use the push() method or the put() method, depending on the type of collection you are working with.

Here is an example using both methods:

Using the push() method:

use Illuminate\Support\Collection;

$collection = new Collection();

$collection->push('element1');
$collection->push('element2');
$collection->push('element3');

print_r($collection->all());

This will output:

Array
(
    [0] => element1
    [1] => element2
    [2] => element3
)

Using the put() method on an associative array collection:

use Illuminate\Support\Collection;

$collection = new Collection();

$collection->put('key1', 'value1');
$collection->put('key2', 'value2');
$collection->put('key3', 'value3');

print_r($collection->all());

This will output:

Array
(
    [key1] => value1
    [key2] => value2
    [key3] => value3
)

Note: If you are working with an instance of a specific Illuminate collection class like Illuminate\Support\Collection, you can add elements to the collection using the push() or put() methods directly on the instance. However, if you are working with a generic Illuminate\Support\Collection instance, you can also add elements using array-like syntax like $collection[] = 'element'; or $collection['key'] = 'value';.
