如何在codeigniter中返回多维数组

$users = array(
    array(
        'name' => 'John',
        'email' => 'john@example.com',
        'age' => 25
    ),
    array(
        'name' => 'Jane',
        'email' => 'jane@example.com',
        'age' => 30
    )
);

class Users extends CI_Controller {
    public function index() {
        $users = array(
            array(
                'name' => 'John',
                'email' => 'john@example.com',
                'age' => 25
            ),
            array(
                'name' => 'Jane',
                'email' => 'jane@example.com',
                'age' => 30
            )
        );

        $data['users'] = $users;

        $this->load->view('users_view', $data);
    }
}

<?php foreach ($users as $user): ?>
    <p>Name: <?php echo $user['name']; ?></p>
    <p>Email: <?php echo $user['email']; ?></p>
    <p>Age: <?php echo $user['age']; ?></p>
    <hr>
<?php endforeach; ?>
