让我们烤点甜饼（做饼图）
成功地安装了PHP地Shockwave Flash支持后,就可以用PHP创建Shockwave文件了。学习的最好方法就是直接跳到程序去，所以下面就让我们看看程序。第一个文件包括怎样使用类的示例代码，同时也显示了如何将一个Flash文件嵌入到HTML文档中。
<?php
// include class needed for flash graph
include("class.pie.flash.php");
mysql_connect ("localhost", "root", "");
$query = "SELECT DISTINCT city_name, COUNT(city_id)
FROM city
GROUP BY city_name;";
$result = mysql_db_query ("hermes",$query);
while ($row = mysql_fetch_array ($result)) {
$city_counts[] = $row["COUNT(city_id)"];
$city_names[] = $row["city_name"];
}
mysql_free_result ($result);
// Instantiate new object
$graph = new flash_pie($city_counts, "city.swf");
// set graph title (should not exceed about 25 characters)
$graph->pie_title("City Results", 30);
// set graph legend
$graph->pie_legend($city_names);
// show graph
$graph->show();
// free resources
$graph->close();
?>

注意，你可以将生成的SWF文件直接返回到浏览器中，而不必一定要像我一样把它写到一个文件中。这可能对测试来说是有用的，但你可能很少用到一个Flash文件，更多的时候你可能想把Flash文件嵌入到HTML文档中。如果你选择直接把Flash文件输出到浏览器中，你可以如下设置header content 类型：
header("Content-type: application/x-shockwave-flash")
并把swf_openfile(filename",...)改成swf_openfile("php://stdout",...)

暂无用Flash图形化数据(二)的评论...
稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！
昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
