我知道这个问题经常出现，但我没有在互联网上的每个教程中找到答案。我不知道那里有什么错误，无论是flash与php之间的连接还是php与MySql之间的连接。 这是我的代码。

请帮我找出错误。我将非常感激并感谢您的回答。预先感谢您。
最佳答案
您需要在服务器端测试您的 PHP/MySQL 连接(只需编写一个带有静态值的 PHP 脚本，看看是否会出现错误)。对于客户端，尝试将这些事件添加到您的加载程序中，它可能会提示您出了什么问题:
phpLoader.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
phpLoader.addEventListener(IOErrorEvent.NETWORK_ERROR, onIOError);
phpLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecurityError);
phpLoader.addEventListener(HTTPStatusEvent.HTTP_STATUS, onHTTPStatus);
private function onIOError(e:IOErrorEvent):void
{
trace("onIOError " + e.toString());
}
private function onSecurityError(e:SecurityErrorEvent):void
{
trace("onSecurityError " + e.toString());
}
private function onHTTPStatus(e:HTTPStatusEvent):void
{
trace("onHTTPStatus statuscode " + e.status + " - " + e.toString());
}
