Constructor Property Promotion

Constructor Property Promotion is a simple shorthand syntax to declare and assign class properties from the constructor. It basically tells the way data has to be treated in code. Constructor Property Promotion is a new syntax provided in the newer version of PHP 8 that allows class property declaration and constructor assignment, variable assignment right from the constructor without getting in the condition of boilerplate code. This avoids having to type the class property name and property type from many to just once. It also avoids using repeated types. Promoted properties can only be used in constructors. Properties will be assigned before the rest of the constructor code is executed.
