==========================
Rule ``phpdoc_separation``
==========================

Annotations in PHPDoc should be grouped together so that annotations of the same
type immediately follow each other. Annotations of a different type are
separated by a single blank line.

Configuration
-------------

``groups``
~~~~~~~~~~

Sets of annotation types to be grouped together. Use ``*`` to match any tag
character.

Allowed types: ``list<list<string>>``

Default value: ``[['author', 'copyright', 'license'], ['category', 'package', 'subpackage'], ['property', 'property-read', 'property-write'], ['deprecated', 'link', 'see', 'since']]``

``skip_unlisted_annotations``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Whether to skip annotations that are not listed in any group.

Allowed types: ``bool``

Default value: ``false``
