$userData = getByName('John Doe'); echo $userData['email'];
$users = [ ['name' => 'John Doe', 'age' => 25], ['name' => 'Jane Smith', 'age' => 30] ]; $userData = getByName('Jane Smith', $users); echo $userData['age'];In this example, the getByName function is used to retrieve user data from an array of users. The second argument passed to the function is the array of users. The user data for the user with the name "Jane Smith" is returned, and their age is then echoed out. It is difficult to determine the package library for the getByName function without more information. It could be part of a custom library or framework, or it could be part of a PHP extension.
