@static
The @static tag declares the decorated element as static — a docblock equivalent of PHP's native static keyword, used where that keyword cannot actually be written. This matters most for magic members declared through @property, which has no way to express staticness itself; @method already has its own inline "static" keyword for magic methods, so a standalone @static tag is mostly relevant elsewhere.
Parsing a @static tag produces a StaticTag instance. Being a pure marker, it adds nothing beyond the $name and optional $description every Tag already carries.
@static is part of the original phpDocumentor tag vocabulary, but phpDocumentor 3 has since dropped it entirely: it is absent from the current tag reference index, and no tags/static.html page exists any longer. Only the archived phpDocumentor 1.x manual still describes it, as a legacy reference rather than current documentation — phpDocumentor 1.x manual, archived. It is supported here for classic-style docblocks.
