This check looks for accesses to local static members using the fully qualified name instead of
self::.While this is perfectly valid, the fully qualified name of
Certificate::TRIPLEDES_CBCcould just as well be replaced byself::TRIPLEDES_CBC. Referencing local members withself::assured the access will still work when the class is renamed, makes it perfectly clear that the member is in fact local and will usually be shorter.
