Flatten multi-dimensional array to array with dot notation in Laravel

Question

I am looking for a way to flatten this array:

$array = ['parent' => ['childA' => "value", 'childB' => "value"]];

to:

$array = ['parent.childA' => "value", 'parent.childB' => "value"];

Is there an elegant way to do this in Laravel? For example with Laravel Collections.

The array_dot() Laravel helper is done exactly for that:

array_dot($array);

The array_dot function flattens a multi-dimensional array into a single level array that uses "dot" notation to indicate depth

For Laravel 5.7 and newer:

take a look at Arr::dot()

For Laravel 5.6 and older:

array_dot is the way to go (see Alexeys answer)
