In PHP 8.1 you can still use Serializable, but only if the implementing class has _serialize() and _unserialize() as well. Instead of broken Serializable interfaces, you’re recommended to use _serialize() and _unserialize() magic methods, which were introduced in PHP 7.4. Deprecated usage of Serializable interfaces Let’s take a closer look at some of the significant deprecations. PhpStorm will help you find deprecated code in your projects and make the upgrade process easier. Every PHP release cleans them up, and 8.1 is no exception as it deprecates a lot of legacy things. PHP has been known for its quirky behavior in some cases. In PhpStorm, convert fromCallable calls to the new syntax by pressing Alt+Enter and choosing a quick-fix from the dropdown list: The advantage is that the new syntax is accessible to static analysis, and it respects the scope at the point where the callable is created. Now you will be able to do the following instead: In PHP 8.1 it will be possible to get a reference to any function – this is called first-class callable syntax. PhpStorm validates all the cases to help you use these new language features: In addition, you cannot use the new operator with class constants because of problems with the initialization order. Or rather, it will be possible to use it via constructor property promotion only, but those are actually parameter arguments, not default property values. In PHP 8.1, objects can be used as default parameter values, static variables, and global constants, as well as in attribute arguments.Ī cool side effect is that nested attributes are now possible with this change.īut you can’t use the new operator with properties.

Enums (available since PhpStorm 2021.2).

This is a good time to report any lingering issues that you’ve encountered, as there is still time to fix them before the release.Ĭheck out the previous posts to see how other PHP 8.1 language updates will be supported in PhpStorm: The Early Access Program is coming to a close, and we are now focusing on stabilizing and polishing PhpStorm for release. There is also a new VCS action: Push All up to Here. To make PhpStorm fully ready for PHP 8.1, we recently introduced support for the `new` operator in initializers, first-class callables, and some major deprecations in the language.
