Chunk multidimensional array by value in Laravel

Have you ever needed to put arrays with same value together? It's super easy using collections in Laravel!

Just imagine you have the following array:

$people = [
    ['name' => 'Alex', 'age' => 25],
    ['name' => 'Martin', 'age' => 32],
    ['name' => 'John', 'age' => 25]
];

And want to put people with same age into same groups. Using collection in Laravel you can do it in one line:

$chunkedByAge = collect($people)->chunkWhile(fn($v, $k, $c) => $v['age'] == $c->last()['age']);

Happy coding!
