| Question: | Comments in your PHP |
| Answer 1: | Should be used liberally to help anyone who has to read your program at a later date understand how it works This was the CORRECT answer |
| Answer 2: | Should be used, but sparsley - if you have a lot of them, they'll have a significant effect on the bandwidth of your server |
| Answer 3: | Should be avoided if at all possible, but you might occasionally use them during development to leave a reminder for yourself of work that's still to be done before your program gets released into a production environment. |
