If you use variables as a objects, you can make a fake empty class with properties and phpDOC for each property, declare the object of that class, and netbeans will autocomplete the properties (keys of the object).
Then in your netbeans code
// will autocomplete with countryName, adminCode1 etc...
?>
Of course if a function is returning $obj and it has the phpDoc @return, there is no need to use the comment @var
