How to use php for linear graph functions

I'm glad you have such a special liking for php (as the mainstream development language! The following describes the functions of php (as the mainstream development language) for linear graph:/* function description & #36; data: Y axis data (array) & #36; graphdata: y-axis data -- percentage (array) & #36; label: x-axis data (array) SyntaxH I'm glad you have such a special liking for php (as a mainstream development language!
The following describes the linear graph functions of php (as the mainstream development language:

/*
Function description
$ Data: Y axis data (array)
$ Graphdata: Y axis data-percentage (array)
$ Label: x-axis data (array)
$ Height: Image height
$ Width: Image width
$ Font: font size
$ Dot: determines the vertex size.
$ Bg: Background color
$ Line: line color
$ Text: text color
$ Dotcolor: spot color
$ File: output image file name
*/

Function qximage ($ data,
$ Graphdata,
$ Label,
$ Height,
$ Width,
$ Font,
$ Dot,
$ Bg,
$ Line,
$ Text,
$ Dotcolor,
$ File)
{
$ Jc = $ height/100;
$ Fontwidth = imagefontwidth ($ font );
$ Fontheight = imagefontheight ($ font );

$ Image = imagecreate ($ width, $ height + 20 );
$ Bg = imagecolorallocate ($ image, $ bg [0], $ bg [1], $ bg [2]);
$ Line = imagecolorallocate ($ image, $ line [0], $ line [1], $ line [2]);
$ Text = imagecolorallocate ($ image, $ text [0], $ text [1], $ text [2]);
$ Dotcolor = imagecolorallocate ($ image, $ dotcolor [0], $ dotcolor [1], $ dotcolor [2]);
Imageline ($ image, 0, 0, $ height, $ line );
Imageline ($ image, 0, $ height, $ width, $ height, $ line );
For ($ I = 1; $ I <11; $ I ++)
{
Imagedashedline ($ image, 0, $ height-$ jc * $ I * 10, $ width, $ height-$ jc * $ I * 10, $ line );
