$image = imagecreatetruecolor(200,200); //创建一张200*200的画布;
//创建多种又区分的颜色
$red = imagecolorallocate($image,255,0,0);
$blue = imagecolorallocate($image,0,0,255);
$yellow = imagecolorallocate($image,255,255,0);
$violet = imagecolorallocate($image,255,0,255);

//使用for循环创建3d效果底层效果
for($i=120;$i>100;$i--){
imagefilledarc($image,100,$i,200,120,0,30,$red,img_arc_pie);//img_arc_pie注释如下:imagefilledarc($image,100,$i,200,120,30,80,$blue,img_arc_pie);
imagefilledarc($image,100,$i,200,120,80,360,$yellow,img_arc_pie);
}
//bool imagefilledarc ( resource image, int cx, int cy, int w, int h, int s, int e, int color, int style )
//
//imagefilledarc() 在 image 所代表的图像中以 cx,cy(图像左上角为 0, 0)画一椭圆弧。如果成功则返回 true,失败则返回 false。w 和 h 分别指定了椭圆的宽和高,s 和 e 参数以角度指定了起始和结束点。style 可以是下列值按位或(or)后的值:
//
//img_arc_pie
//
//img_arc_chord
//
//img_arc_nofill
//
//img_arc_edged
//这个层是最上面一层的效果,这样立体效果就出来了!
imagearc($image,100,100,200,120,0,360,$black);//添加一个黑色的边圈,这样3d效果看起来更加明显点
imagefilledarc($image,100,100,200,120,0,30,$red,img_arc_pie);
imagefilledarc($image,100,100,200,120,30,80,$blue,img_arc_pie);
imagefilledarc($image,100,100,200,120,80,360,$yellow,img_arc_pie);//添加百分比数据,当然此处必要的时候可以批量的进行一定的运算将输入输入到图片上
$str = iconv ("gbk","utf-8","36%");//如果要输入中文需要此转换。example:占用:30%;
imagettftext($image,10,360-15,100+70,115,$white,"simhei.ttf",$str);
imagejpeg($image);
imagedestroy($image);

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
