         1、利用php gd库的函数绘制3D扇形统计图
50; $i--)
  {
imagefilledarc($image, 50, $i, 100, 50, -160, 40, $darknavy, );
imagefilledarc($image, 50, $i, 100, 50, 40, 75, $darkgray, );
imagefilledarc($image, 50, $i, 100, 50, 75, 200, $darkred, );
  }
  /*画椭圆弧并填充*/
  imagefilledarc($image, 50, 50, 100, 50, -160, 40, $darknavy, );
  imagefilledarc($image, 50, 50, 100, 50, 40, 75, $darkgray, );
  imagefilledarc($image, 50, 50, 100, 50, 75, 200, $darkred, );

  /*画字符串*/
  imagestring($image, 3, 15, 55, "30%", $white);
  imagestring($image, 3, 45, 35, "60%", $white);
  imagestring($image, 3, 60, 60, "10%", $white);

  /*输出图像*/
  header("content-type:image/png");
  imagepng($image);

  /*释放资源*/
  imagedestroy($image);
  ?>
效果：
