This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function. It has, however, found a similar but not annotated parameter which might be a good fit.
Consider the following example. The parameter
$ireland
is not defined by the methodfinale(...)
.The most likely cause is that the parameter was changed, but the annotation was not.
