This little enhancement would save much time.

Scenario:
- both functions do not exist

......
 $obj->someNewFunction($var->id);
 $obj->anotherNewFunction($id);
......

Trigger hint dialog and select "Create function"

Netbeans will create function(s):

 someNewFunction($param0)
 {
 }

 anotherNewFunction($id)
 {
 }

I thinkit would be better, if Netbeans instead of "pamar0" named the parameter after the variable:

 someNewFunction($varId)
 {
 }
