PhpStorm 2018.3.1 RC 183.4588.24

Roman Pronskiy

Last week we released PhpStorm 2018.3, and today we are ready to give you the first RC build for the upcoming 2018.3.1 update. Please give PhpStorm 2018.3.1 build 183.4588.24 a try and share your feedback with us.

This build delivers new features including support for custom string format functions and improved handling of @internal annotations. It also has some bug fixes and improvements for PHP and the Web, and takes on the latest improvements in IntelliJ Platform.

Support for custom string format functions

In PhpStorm 2018.3, we improved the way sprintf() and printf() functions are handled – their parameters and placeholders under the caret are highlighted. In this update, we are taking another step forward: you can now define your own custom string formatting functions, and PhpStorm will apply appropriate highlighting to them, too.

To add custom formatting functions, go to Settings / Preferences | Languages & Frameworks | PHP | Analysis. There, expand the Custom Format Functions node and add a new item:

add_custom_format_function

You can add both class methods and plain functions, and PhpStorm will provide you with code completion in both cases. Then, specify the index of the argument where your formatting template resides.

That’s it: apply your changes, and your custom formatting function will be included in the analysis:

add_custom_format_function_example

Improved @internal annotation handling

In this update, we’ve improved the behavior of the Usage of internal entity inspection, which handles @internal annotations.

Previously, marking a class as internal would result in all class usages marked as internal, too.

internal-class-usage

Now, since @internal commonly denotes elements internal to a package or a library, the inspection takes your actual project structure into account:

In a project with no source roots, no @internal class usages will be marked.
If a source root is configured and the @internal class is located inside it, the usages inside this source root won’t be marked, but usages outside this source root will be marked.
If the @internal class is located inside a library, all its usages outside libraries will be marked.
In a Test Sources root, no @internal elements’ usages will be marked.
