Let me introduce myself again.
I was a newbie. At that time, I learned php purely to cope with the leadership. Let's make a statistical chart. I originally learned asp and suddenly changed the line. However, php is really powerful, well, I can't leave him anymore. No, I have fixed all the pie charts and column charts, but I still have a lot of questions. I hope you can give me more advice and talk a lot of nonsense, I thought it was writing a letter.
