This means that if you add the # attribute in a separate line in your PHP 7.* project, the PHP interpreter will parse it as just a line comment and you won’t get a parse error. What about legacy projects that can’t upgrade to PHP 8?įortunately, the syntax of one-line attributes is backward compatible. You can extract an array that defines a shape into a constant and then reuse it inside the attributes where it applies: const MY_ARRAY_SHAPE = Starting from PhpStorm 2020.3, it will be possible to define the structure of such arrays with an #.Īs you can see, the ‘type’ can be specified as a scalar in a string or as a class reference in the form of an FQN string or a ::class constant. This functionality could be useful when working with simple data structures or object-like arrays when defining a real class may feel excessive. This was partially implemented with Psalm support.īut the other part – specifying the possible keys and what value type they correspond to – was still missing. One of the most requested features for PhpStorm was support for more specific array PHPDoc annotations. Replacement: '%class%->setPublic(!%parameter0%)' Reason: 'since Symfony 5.2, use setPublic() instead', With # attribute we can make migration easier. In Symfony 5.2 the \Symfony\Component\DependencyInjection\Alias::setPrivate() will be deprecated. Let’s take a look at a real-world example.
If you specify the reason argument for the attribute, then it will be shown to a user in the inspection tooltip. That will help users of the deprecated functionality migrate. The main advantage of this new attribute is that you can specify replacement for functions and methods. This attribute is similar to PHPDoc tag and is used to mark methods, functions, classes, or class constants and it indicates that they will be removed in future versions as they have become obsolete. The design of the attributes below is still a work in progress, and your feedback is very welcome. And # is a highly anticipated evolution of PHPDoc’s array description. # and # are more advanced descendants of. Several attributes will be available in PhpStorm 2020.3 under \JetBrains\PhpStorm\ namespace. What attributes will be available in PhpStorm 2020.3? For attributes that you define, you have to implement their behavior yourself. What attributes are in PHP 8?Īpart from the syntax definition and validation when calling ReflectionAttribute::newInstance(), PHP 8 does not provide any attributes out-of-the-box.
But just in case you haven’t, they are the new format for structured metadata that replaced PHPDoc and will now be part of the language. You’ve probably already heard about the attributes in PHP 8. Read on to learn more about the attributes, and please share your feedback about the design. PhpStorm 2020.3 will come with several PHP 8 attributes available out-of-the-box:
