Is it possible to assign keys to array elements in PHP from a value column with less code?

Question

Let\'s assume I have an array of elements, which are arrays themselves, like so:

$array = [
    [\'foo\' => \'ABC\', \'bar\' => \'DEF\'],
    [\'foo\'          


        

Answer 1

Notice array-column can get index as well (third argument):

mixed $index_key = NULL

So just use as:

array_column($array, null, 'foo');
