Exercise : 12 Days of Xmas

Modify the following HTML to display the lyrics of the song, "12 Days of Xmas," along with displaying images for each of the gifts given on each day. The page already has the correct appearance, but the code is long and redundant. Modify the page to use PHP code to remove this redundancy.

Exercise development strategy

1. For each day # N, show day N's gift image once.
2. For each day # N, show day N's gift image N times.
3. For each day # N, show (day N's down to day 1's) gift image the right # of times.

• 12days.php (source)
• 12days-advanced.php (source) (uses some syntax we haven't seen yet)
