PHP 8.0 Features

Constructor Property Promotion

Declare and assign properties directly in the constructor signature — eliminates boilerplate. Heavily used in Magento service classes.

Named Arguments

Call functions with parameter names: array_slice(array: $arr, offset: 2). Improves readability for functions with many parameters.

Match Expressions

Type-safe switch replacement that returns a value. No fall-through, strict comparison. Better than switch for value mapping.
