php如何将数组对象转为对象数组

$user = [    'id' => 1,    'name' => 'Jack',    'age' => 28,];

class User {    public $id;    public $name;    public $age;    public function __construct($id, $name, $age) {        $this->id = $id;        $this->name = $name;        $this->age = $age;    }}

function arrayToObject($array) {    $objectArray = [];    foreach ($array as $item) {        $user = new User($item['id'], $item['name'], $item['age']);        array_push($objectArray, $user);    }    return $objectArray;}

$users = [    [        'id' => 1,        'name' => 'Jack',        'age' => 28,    ],    [        'id' => 2,        'name' => 'John',        'age' => 32,    ],    [        'id' => 3,        'name' => 'Lily',        'age' => 25,    ],];$objectArray = arrayToObject($users);

foreach($objectArray as $user) {    echo $user->name . ' is ' . $user->age . ' years old.';}
