Can you give an example of the latest updates and new features added to PHP?

Recent versions of PHP have introduced several important features and improvements:

• PHP 8.1 introduces enumerations (Enums), allowing the creation of sets of named constants with type safety.
• Readonly properties have been added, which can only be initialized once.
• Fibers, primitives for cooperative multitasking, have been introduced to enable writing asynchronous code.
• Performance has been improved and type support has been extended, for example, with the addition of the "never" type.
• PHP 8.2 features readonly classes, improvements in deprecation notices, and new functions such as random_* for generating random numbers.

Example of using enumerations in PHP 8.1:

enum Status: string {
    case Draft = 'draft';
    case Published = 'published';
    case Archived = 'archived';
}

function publish(Status $status) {
    if ($status === Status::Draft) {
        // publication logic
    }
}

publish(Status::Draft);
