PHP使用简单的函数转换数组

Question

Would there be a simple native PHP function that would transform this array:

Array
(
[0] => stdClass Object
    (
        [id] => 1
        [module_libelle] => Qualités esthétiques
    )

[1] => stdClass Object
    (
        [id] => 2
        [module_libelle] => Qualités pragmatiques
    )
...
 )

in this array:

Array
(
[1] => Qualités esthétiques
[2] => Qualités pragmatiques
...
)

without function like foreach?

Answer 1

If you also want to keep the id as the array key in the result array, you might use array_walk

$result = array();
array_walk($array, function ($value) use (&$result) {
    $result[$value->id] = $value->module_libelle;
});

print_r($result);

Demo

Or you might use array_reduce:

$array = array_reduce($array, function($carry, $item) {
    $carry[$item->id] = $item->module_libelle;
    return $carry;
});

print_r($array);
