In what situations should developers prioritize using array keys over other data structures in PHP?

Developers should prioritize using array keys over other data structures in PHP when they need to quickly access and retrieve values based on specific identifiers. Array keys provide a simple and efficient way to store and access data in a structured manner, making it easier to organize and manipulate information within the array. 

// Example of using array keys to store and access data
$userData = [
    'id' => 1,
    'name' => 'John Doe',
    'email' => 'johndoe@example.com'
];

echo $userData['name']; // Output: John Doe
