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

You can also do it with array_reduce

$new_array = array_reduce($array, function($carry, $item) {
    $carry[$item['foo']] = $item;
    return $carry;
}, []);
