PHPとMySqlのflash as3.0（flash pro）との接続

Question

この質問は頻繁に起こりますが、インターネット上のすべてのチュートリアルで答えが見つかりませんでした。私はそこに間違いがあるかどうか、MySQLとのPHPまたはPHPとフラッシュの間の接続かどうかわからない。 これは私のコードです。

私は、データベースを作りました。

は、障害を見つけるために私を助けてください。私は非常に感謝し、あなたの答えに感謝します。前もって感謝します。

サーバー側でPHP/MySQL接続をテストする必要があります（静的な値を持つPHPスクリプトを作成し、エラーが発生するかどうかを確認するだけです）。クライアントサイドでは、これらのイベントをローダに追加しようとすると、何が間違っているのかを知ることができます。

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()); 
    }
