How to convert an associative array to a normal one?

Question

PHP

Good day.
The point is this. There is an associative array of the form: Can it be somehow converted into this form: ? I found some kind of stupor, or I don’t understand something) Thank you all.
$arr = [ 0 => 'a', 1 => 'b', 2 => 'c']
['a', 'b', 'c']

Answer 1

[ 0 => 'a', 1 => 'b', 2 => 'c'] this is ['a', 'b', 'c']. Simply in the first case you explicitly specify indexes.

Answer 2

In general, the comment was correct, you wrote equivalent arrays, provided that in the first case it is numeric keys. not strings.
In all other cases it will help: array_values()
