| Enforces rules related to the formatting of DocBlocks ("Doc Comments") in PHP code. | ||
| DocBlocks are a special type of comment that can provide information about a structural element. In the context of DocBlocks, the following are considered structural elements: | ||
| class, interface, trait, enum, function, property, constant, variable declarations and require/include[_once] statements. | ||
| DocBlocks start with a `/**` marker and end on `*/`. This sniff will check the formatting of all DocBlocks, independently of whether or not they are attached to a structural element. | ||
