The evolution of PHP  ## Metadata - Author: [[PHP Annotated]] - Full Title: The evolution of PHP - Category: #articles - Document Note: 1. What benefits does the evolution of PHP bring? 2. What specific features have been added in each version of PHP? 3. How does the use of read-only properties benefit developers? PHP has evolved significantly over the past decade, from simple data transfer objects in PHP 5.6 with properties, constructor, and getters, to more advanced features in PHP 8.2 such as type properties, read-only properties, and a shortcut for classes with read-only properties. These changes have allowed for improved encapsulation and less verbose code. - Summary: I've got a pretty good example to illustrate how much PHP has changed over the past decade. - URL: https://www.youtube.com/watch?v=x9bSUo6TGgY&ab_channel=PHPAnnotated i want to show you how much php hasevolved over the years and i've got apretty good example let's take a look atyour average data transfer object backin php 5.6 it had properties aconstructor and some getters and this iswhat i would call a properobject-oriented approach the data isencapsulated and properly typed nowmoving on to php7.0 where scalar types and return typesare added nullable types aren't a thingyet so we still need to use dog blocks for our published field over there andthat brings us to php 7.1 where we gotnullable types which allowed us to getrid of many of those verbose doc blocksas well next were php 7.2 and 7.3 whichdidn't really bring any changes for ourexample but then came php 7.4 whichintroduced type properties and so we canfinally get rid of all duck blocks butwe're not done yet php 8.0 came alongand introduced promoted properties whose sole purpose was to get rid of boringcode property definitions andassignments can now all be combinedwithin the constructor and then php 8.1introduced read-only properties whichmeans that we don't really need anygetters anymore we can still ensureproper encapsulation without all thosemethods and finally there's php 8.2which will be released later this yearit has a shortcut for classes that onlycontain read-only properties which is a common case when working with datatransfer objects you can now mark aclass as read-only and it will apply toall its properties automatically andthat is part of the evolution of phpover a decade in two minutesby the way would you mind leaving a likedown below thank youyou, The evolution of PHP, PHP Annotated, 01gq01yzrtkpv1bwhkzd5957zk.
