Currently in RC3, PHP 7.2 is planned to be released on November 30. The new release is coming with new features, functions, and improvements that will allow us to write better code. In this post, I will introduce some of the most interesting language features coming with PHP 7.2.

You can see the full list of upcoming changes on the Requests For Comments page.

Their list covers a number of the updates coming in this version including:

  • Argument type declarations [for objects]
  • Parameter Type Widening
  • Trailing commas in list syntax
  • Several security improvements

Martin Hujer:
PHP 7.2 is due in November. What's new?
Sep 12, 2017 @ 10:15:58

In a new post to his site Martin Hujer looks ahead at the next major release for the PHP language - PHP 7.2 - and what new features and changes are coming with it.

PHP 7.2 is planned to be released on 30th November 2017 (see the timetable). And it comes with two new security features in the core, several smaller improvements and some language legacy clean-ups. In the article, I will describe what the improvements and changes are. I read the RFCs, discussions on internals and PRs on Github, so you don't have to.

Among the changes he lists are updates like:

  • Argon2 Password Hashing
  • Make Libsodium a Core Extension
  • Object typehint
  • Counting of non-countable objects

He also lists out some of the things that will be deprecated in 7.2 including parse_str without a second argument, create_function, mbstring.func_overload and asset with a string argument. You can check out these and other other changes coming (along with code examples) in the full post.

Zend Developer Zone:
Deprecations in PHP 7.2
Jun 28, 2017 @ 11:20:50

On the Zend Developer Zone there's a new post sharing some of the deprecations coming with PHP 7.2, the next release in the 7.x series (planned release sometime later this year).

PHP is a living language and as such, as some things are added, others are removed. Since PHP adheres to the best practice of Semantic Versioning, nothing will be going away in PHP 7.2, but some things will be marked as “Deprecated” so that developers can start removing them from their code and finding better ways to get the job done.

PHP 7.2 brings us a new list of things that will be eventually going away. The complete list, as well as explinations and voting can be found at “PHP RFC: Deprecations for PHP 7.2

They include a "hit list" of the functionality that will be affected including the removal of support for __autoload, the create_function function, removal of assert and the (unset) cast. The RFC has been moved to the "Accepted" state so now work will be done to make these and other deprecations happen in this next great release.

Laravel News:
Deprecations for PHP 7.2
Jan 31, 2017 @ 11:15:06

In this new post to the Laravel News site they list out some of the deprecations coming in PHP 7.2 based on this RFC.

The PHP 7.2 RFC for deprecating some current functionality has been approved. The following items are included in this list and will begin throwing deprecated notices.

The list of features to be deprecated includes:

  • the magic __autoload function
  • the create_function function
  • the (unset) cast
  • the each function

Most of the things in the list are functionality that you just don't see much in recent PHP development. It could cause problems for older codebases but for those already on PHp 7 it shouldn't take much to make the necessary changes.

Matthew Weier O'Phinney:
On Deprecating ServiceLocatorAware
Apr 27, 2016 @ 11:16:51

In this post to his site Matthew Weier O'Phinney talks about a change in the Zend Framework ZendMVC package to deprecate the ServiceLocatorAware interface and some of the unexpected backlash of it.

A month or two ago, we pushed a new release of zend-mvc that provides a number of forwards-compatibility features to help users prepare their applications for the upcoming v3 release.

One of those was, evidently, quite controversial: in v3, zend-servicemanager no longer defines the ServiceLocatorAwareInterface, and this particular release of zend-mvc raises deprecation notices when you attempt to inject a service locator into application services, or pull a service locator within your controllers.

He shares some of the "constructive" feedback they received when they made the change, most importantly asking for a justification for the change. He then goes through their thinking behind the change, some of its original intent and how it allowed for "dependency hiding" in its use. He gets into some detailed code examples for this last point, some of the errors that could happen as a result and other issues (like no type safety and the brittleness of using a service locator).

Symfony Blog:
New in Symfony 3.0
Mar 16, 2016 @ 09:39:21

On the Symfony blog there's a new post briefly looking at Symfony 3 and what's different about it as compared to previous releases (and what's not).

Symfony 3.0.0 was released on November 2015 as planned by the Symfony 3 roadmap. As we do with any new Symfony version, we should publish a blog series explaining its new features.

However, Symfony 3.0 is a very special version which contains no new features comparing it with Symfony 2.8. Their only difference is that 3.0 removed any feature marked as deprecated in 2.8. That's why we won't publish any "New in Symfony 3.0" post. Instead, let's do a quick recap of the new Symfony 2.8 features which are also available on Symfony 3.0.

Among the items on their list are things like:

  • New components like Guard Authentication and LDAP
  • A MicroKernel component
  • Improvements for VarDumper, Console and the Security components

Each of the changes on their list include links to get more information about the component and the post wraps up with a quick "how-to" on upgrading to Symfony 3 from other releases.

Symfony Blog:
Paving the way for Symfony 3 with the "Deprecation Detector" tool
Oct 22, 2015 @ 10:48:31

On the Symfony blog there's a post talking about a tool they've introduced that is helping to "pave the way" for the upcoming version 3 release of the Symfony framework - the Deprecation Detector tool.

Symfony 3 will be released at the end of November 2015. Learning from our own history, the transition from Symfony 2 to 3 will be much more pleasant than the transition from symfony 1 to 2 that happened in July 2011.

Technically speaking, Symfony 3 includes no new features comparing it with Symfony 2.8, which will be released at the same time. [...] This means that your Symfony applications won't work on Symfony 3 unless you remove all their deprecations. In order to simplify the task of finding which deprecations affect your applications, a new tool called Deprecation Detector has just been released.

The tool runs static analysis against your codebase and finds locations where you're using deprecated methods/classes/interfaces/etc and reports them back for fixing. The post includes the commands you'll need to get the tool installed and how to run it against your code. You can find out more about the project and get details on command line options on its GitHub repository.

Symfony Blog:
Twig: How to upgrade to 2.0? Deprecation Notices to the Rescue
Aug 19, 2015 @ 10:55:58

The Symfony blog has posted a quick guide with a tip to upgrading to Twig 2.0 made simpler thanks to some built-in deprecation notices.

As Twig 2.0 is approaching fast now, it's time to focus on how to boost adoption of this new major version. [...] Also, the good news is that most of the time, it's possible to make your code work for both major versions (that's important for shared code like bundles). [...] How to make it easy? Like for Symfony, I've now added deprecation notices throughout the code to give Twig users an easy way to upgrade their code (this is available in the upcoming Twig 1.21 version).

The release of v1.21 comes with the deprecation notices already built-in making it easy to find the issues before making the jump up to v2.0. He also includes mentions of two other things included to make it easier: a deprecation collector to gather the issues in one place and a visitor base class diff that can make them compatible with both versions (1.21 and pre-1.21).

PHP.net:
PHP7 Migration Guide Posted
Aug 17, 2015 @ 11:29:48

The official PHP.net has posted their PHP 7 migration guide for those already on PHP 5.6.x and wanting to prepare their applications for PHP7.

Despite the fact that PHP 7.0 is a new major version, efforts were put in to make migration as painless as possible. This release focusses mainly on removing functionality deprecated in previous versions and improving language consistency. There are a few incompatibilities and new features that should be considered, and code should be tested before switching PHP versions in production environments.

The guide includes links to other pages showing things like:

  • Backward incompatible changes
  • New features
  • Deprecated features in PHP 7.0.x
  • New functions/classes/interfaces/global constants
  • Removed Extensions and SAPIs

There's also a link to some other various changes that's not completely fleshed out yet, but is evolving as PHP 7 gets closer to a final release.
