Extract a particular key values to separate array in PHP

Question

The array structure is like this

    $array1 = [
   "101" => [
        "name" => "Robin",
        "age" => "25"
    ],
    "102" => [
        "name" => "asRobin",
        "age" => "25"
    ],
    "103" => [
        "name" => "Roasbin",
        "age" => "25"
    ],
    "104" => [
        "name" => "Robiasn",
        "age" => "25"
    ]
  ]

Here I got the ids in a particular array using $ids = array_keys($array1) function. Now likewise how can i extract the names

What do you want to do with them when you have them?

With array_map :

$names = array_map(function($a) { return $a["name"]; }, $array1);

EDIT : I just remembered that function, which gives a more elegant way to do that :

$names = array_column($array1);
