has no explicit notion of declaring a variable, accessing it before a value is assigned
to it is most likely a bug.

It is not recommended to use PHP's closing tag ?> in files other than templates.
Using a closing tag in PHP files that only contain PHP code is not recommended
as you might accidentally add whitespace after the closing tag which would then
be output by PHP. This can cause severe problems, for example headers cannot be
sent anymore.
A simple precaution is to leave off the closing tag as it is not required, and
it also has no negative effects whatsoever.
This check looks from parameters that have been defined for a function or method, but which are not used in the method body.
