This RFC proposes to allow defining constants in Traits. ![]() To get around this limitation, you need to define constants in its composing class or an interface implemented by its composing class. That means you cannot define invariants expected by a Trait within the Trait itself. They’re great for code reuse across classes.Ĭurrently, Traits only allow defining methods and properties, but not constants. From of version 9.8 and on, Scriptcase and.

The release workflow will push it and tag it under 6.0.0.80. Run Rector on the source code with this config: vendor/bin/rector process /src -config rector-downgrade.phpĪfter Rector finishes, the code in /src will have PHP 8.0 syntax. RPM are available in the remi-php81 repository for Fedora 33 and. A whole bunch of optimized and well tested C functions that are typical of backend functionality. A great thanks to all developers who have contributed to this new major and long awaiting version of PHP and thanks to all testers of the RC versions who have allowed us to deliver a good quality version. We want to enjoy the latest features, so we bump our composer.json: RC6 was GOLD, so version 8.1.0 GA is just released, at planed date. The new Symfony and Laravel 9 are released.
