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.

The boss rushed and couldn't help it. The pie chart function was released. You can grab it soon.

Function Description
$ Chartdata: data, which is an array element
$ Chartfont: font size
$ Chartdiameter: determines the size of the pie (It depends on whether you are hungry, huh, huh)
$ Chartlabel: title, also an array element
$ Colorslice: color array, for example, $ TMP = array255, 255,255); $ colorslic = array ($ TMP );
$ Colorborder: border color, array
$ Colortext: text color, array
$ Colorbody: background color, array
$ File: output image file name */
