Are there best practices for defining array keys and values in PHP?

When defining array keys and values in PHP, it is best practice to use meaningful and descriptive keys to make the code more readable and maintainable. Additionally, it is important to ensure that keys are unique to avoid overwriting values. Using constants or variables as keys can also help improve code organization and reusability. 

// Example of defining an array with meaningful keys and values
$user = [
    'name' => 'John Doe',
    'email' => 'john.doe@example.com',
    'age' => 30
];
