I now have a table like this. The numbers in it are ages, which are read from the database. The following is the php code

The effect I require now is to divide the colors according to the zodiac (for example: 01, 13, 25, 37, 49 is a chicken, just write chicken below the age, the background color is red. 02, 14, 26, 38 If you are a monkey, just write monkey below the age, the background color is blue, and so on...), the following is the rendering I made with PS

Is there any master who can help me? I just learned PHP and I still don’t understand the basics of PHP. I hope the master can give me some advice. Thank you very much.
