push array data and find the index of array

Question

how can i create a empty array that i can push users information such as:

$users->set('bob', array('email' => '[email protected]', 'password' => '123456'));
$users->set('joe', array('email' => '[email protected]', 'password' => 'test'));

and retrieve/read the keys i want to read like:

$user = $users->get('bob');
echo 'Bob, your email is ' . $user['email'];

and also be able to retrieve all key names

$keys = $users->getKeys();

i have searched google but nothing worked right. Please show me how so i can learn more..

PS: It would also be nice to learn how to delete keys from the array like:

// Delete a key
$users->delete('joe');

i need a system, but what does $users contain? what did you define it as — user1341993

To do it with your syntax, you need to define a class. The class contains an array property, and the get and set methods access the array using normal PHP syntax. — Barmar

You can't do it without a class. The -> syntax only works with classes. — Barmar

Just use ordinary array syntax:

$users['bob'] = array('email' => '[email protected]', 'password' => '123456');

$user = $users['bob'];

$keys = array_keys($users);

unset($users['joe']);

How does this help with ->get and ->set?
