1. Add comment for function
when you have wrote a function in a class, you may want to add comment for this function
At this time, you can click "alt + enter" in the function {}, to create comment.
Please notice that you'd better click the hotkey after you have wrote the function.
Because the hotkey will accord your function to add comment, if there are two params in your function,
it will add @params $a, @params $b and so on.

echo "<html>" // At this time, click "alt + enter"
