I’ve done my own benchmarks on real-life web applications, and it seems like the JIT doesn’t make that much of a difference, if any, on those kinds of PHP projects. The JIT - just in time - compiler promises significant performance improvements, albeit not always within the context of web requests. Furthermore, nullable unions can be written using |null, or by using the existing ? notation: public function foo(Foo|null $foo): void Note that void can never be part of a union type, since it indicates “no return value at all”. public function foo(Foo|Bar $input): int|float Union types are a collection of two or more types which indicate that either one of those can be used. Given the dynamically typed nature of PHP, there are lots of cases where union types can be useful. Let’s start with all new features, it’s quite a list! And don’t worry, all these deprecations are listed in this post.īesides breaking changes, PHP 8 also brings a nice set of new features such as the JIT compiler, union types, attributes, and more.
Php 8 vs php 7 performance upgrade#
If you’ve kept up to date with the latest releases though, the upgrade shouldn’t be too hard, since most breaking changes were deprecated before in the 7.* versions.

CloudBees Rollout is a secure, scalable feature management platform. Right now PHP 8 is in feature freeze, meaning no new features can be added anymore. It’s a new major version, which means that it will introduce some breaking changes, as well as lots of new features and performance improvements. PHP 8 will be released on November 26, 2020. Public function handle(int|string $id, array $query, array $body): Route JIT Compiler, JSON extension always activated, Union Types, Static return type, WeakMap, Use ::class for objects, Stringable interface, Convert DateTime, Type annotations, Type errors… #
The new version of PHP is expected to come with some new features that offer web developers many additional possibilities. After a lot of to-ing and fro-ing as to when PHP 8 would be released, the developers have now announced that November 26th, 2020 is the date we’re waiting for.
