[PHP-DOC] note for functions that return false and "" From: jim winstead (jimw <email protected>)

it would be nice if we had a note we could drop into functions that
return false in failure conditions, but can also return non-failure
values that evaluate to false. perhaps something that included a
reference to a section explaining the situation and how to use the ===
operator to handle it.
