What’s New in PHP 8.1?

PHP 8.1 introduces several new features and improvements, including:

  • Enums: A typesafe way of defining a type with a finite set of values.
  • Fibers: A solution for running asynchronous code using synchronous syntax.
  • Never Return Type: Useful for indicating that a function will not return a value.

Installing PHP 8.1

To install PHP 8.1 on your system, you can follow these steps:

  1. Windows Users: Download the PHP 8.1 VC15 x64 Non Thread Safe version from the PHP Downloads page.
  2. Mac Users: Use Homebrew by typing brew install php@8.1 in your Terminal.
  3. Linux Users: Use the package manager of your distribution to install PHP 8.1.

Exploring Key Features

Now that PHP 8.1 is installed, let’s explore its key features:

Enums

Enums are used to create a type that consists of a finite set of values. Here is an example:

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

Fibers

Fibers allow developers to write asynchronous code using a more traditional, synchronous coding style. Here’s a basic example of how fibers can be used:

$fiber = new Fiber(function (): void {
    echo "Running inside the fiber\n";
});

$fiber->start();

Never Return Type

The never return type is used to indicate that a function does not return. The function either throws an exception or ends the script’s execution. Here is an example:

function redirect(string $url): never {
    header('Location: ' . $url);
    exit;
}

Getting the Best Out of PHP 8.1

To make the most out of PHP 8.1, it’s important to follow these best practices:
