Hey PHP fans! This article highlights some excellent new features of our favorite scripting language. Whether you're a seasoned pro or just starting out, these will make your coding life easier and more fun. Let's dive into the top PHP features you can use right now!

1. Readonly Properties

Let's say you don't want changes to a variable after initialization. Now, with readonly properties, you can set a property once and prevent it from being modified.

class User {
    public readonly string $username;

    public function __construct(string $username) {
        $this->username = $username;
    }
}

2. Enums

Enums are now a thing in PHP! They let you define a set of named values, perfect for things like statuses or categories.

enum Status {
    case PENDING;
    case ACTIVE;
    case INACTIVE;
}

$status = Status::ACTIVE;

3. Match Expressions

Match expression is a more flexible alternative to switch statements. They let you return values directly from each case.

$status = 'active';

$message = match ($status) {
    'active' => 'The user is active.',
    'inactive' => 'The user is inactive.',
    'pending' => 'The user is pending.',
    default => 'Unknown status.',
};

4. Constructor Property Promotion

Save time by defining and initializing properties directly in the constructor.

class Point {
    public function __construct(
        public float $x,
        public float $y
    ) {}
}

$point = new Point(1.5, 2.5);

5. Named Arguments

Named arguments make your code more readable by allowing you to pass values to a function by name instead of position.

function createUser(string $username, bool $isAdmin = false) {
    // Your code here
}

createUser(username: 'john_doe', isAdmin: true);

6. Nullsafe Operator

Avoid those annoying null checks with the nullsafe operator, which lets you call methods or access properties on an object only if it's not null.

$user = getUser();
$profile = $user?->getProfile()?->getBio();

7. Union Types

Type hinting just got more flexible with union types, allowing you to specify multiple types for a parameter or return value.

function processNumber(int|float $number): int|float {
    return $number * 2;
}

8. Array Unpacking with String Keys

Array unpacking with string keys, making it easier to merge arrays.

$array1 = ['a' => 1, 'b' => 2];
$array2 = ['c' => 3, ...$array1];

print_r($array2);
// Output: ['c' => 3, 'a' => 1, 'b' => 2]

9. JSON_THROW_ON_ERROR

With PHP 8.3, you can enable json.exceptions to throw JsonException by default on JSON errors.

ini_set('json.exceptions', '1');

try {
    $data = json_decode('{"invalidJson":}', true);
} catch (JsonException $e) {
    echo 'JSON Error: ' . $e->getMessage();
}

10. JIT Compilation

Just-In-Time (JIT) compilation is now part of PHP, making your scripts run faster by compiling parts of the code at runtime.
