推荐答案

你必须使用 AS3 Loader 类来做到这一点.加载器类应该加载 php 脚本.PHP 脚本应该从 MySQL 数据库加载图像并显示它.它可能看起来像这样:

you have to use AS3 Loader class to do that. Loader class should load php script. Php script should load image from MySQL database and display it. It could look like that:

AS3:

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, ImageLoaded);
loader.load(new URLRequest(urlToYourPhpScript));

function ImageLoaded(e:Event) {
    addChild(e.target.loader.content);
}

其中 urlToYourPhpScript 可以包含一些 get 变量来识别您的图像:urlToYourPhpScript = 'http://www.example.com/?imageid=10'

where urlToYourPhpScript can contain some get variables to identify your image: urlToYourPhpScript = 'http://www.example.com/?imageid=10'

PHP:

$link = mysql_connect("localhost", "username", "password") or die("Error: " . mysql_error());

// select our database
mysql_select_db("test") or die(mysql_error());

// get the image from the db
$sql = "SELECT image FROM images WHERE id=".$_GET['imageid'];

// the result of the query
$result = mysql_query("$sql") or die("Query error: " . mysql_error());

// set the header for the image
header("Content-type: image/jpeg");
echo mysql_result($result, 0);

// close the db link
mysql_close($link);

其中 $_GET['imageid'] 是从 AS3 传递的用于识别图像的参数.

where $_GET['imageid'] is a parameter passed from AS3 for identyfying your image.
