Union Types in PHP 8 allow you to declare multiple types for properties, function arguments, and return types. Before PHP 8, you could only specify a single type for these elements. Let’s explore how union types work: To define a union type, separate the types using the vertical bar (|) We have a method that accepts string and array as a parameter. Nullable Types and Union Types: PHP already supports nullable types using the ? prefix: We have a method that returns a string or null. We can use string|null: When we have multiple return types, 3 or more, we need to specify |null as in the example above. Void Type and Union Types: The void type is allowed only as a single return type. (since it indicates a function that doesn’t return a value). In PHP 8, the void type cannot be combined with any other kind in a union (e.g., string|void isn't allowed). We have an example below with the error: A method with a type combination of string and void. An error happened when I tried to exec...

PHP 8 introduced several powerful features that improve code readability, maintainability, and performance. Two of the most notable features are Constructor Property Promotion and the match expression . These additions simplify common coding patterns and reduce boilerplate code. Let's explore how they work and why they are beneficial. 🔹 Constructor Property Promotion Before PHP 8, defining properties in a class required repetitive code. Developers had to manually declare properties, assign them in the constructor, and often create getter/setter methods. ✅ Traditional Constructor in PHP 7 class User { private string $name; private int $age; public function __construct(string $name, int $age) { $this->name = $name; $this->age = $age; } } ✅ Constructor Property Promotion in PHP 8 With PHP 8, you can define and assign class properties directly in the constructor parameters using the public, protected, or private keywords. class User { publ...
