After hard work, pie3d is completed, and the good stuff is shared with everyone. However, I am new to PHP and the code may not be refined enough. I hope everyone can give me some advice and work together to improve this program. Remember to notify me (estorm@yeah.net)

The above introduces the implementation code of the PHP three-dimensional pie chart of the Pokemon Dark Phantom cheat code, including the content of the Pokemon Dark Phantom cheat code. I hope it will be helpful to friends who are interested in PHP tutorials.
