カスタムヘルパーの有無にかかわらずZend_Cache/Zend_Registryにインスタンスを保存する

2011-08-07 1 views

Zend_Log（Zend_Log_Writer_Streamを含む）のインスタンスをZend_Cache（推奨）またはZend_Registry（フォールバック）に保存しようとしていますが、代わりにカスタムヘルパーを抽象レイヤー直接アクセスの。カスタムヘルパーの有無にかかわらずZend_Cache/Zend_Registryにインスタンスを保存する

直接除き、Zend_Registryを使用している場合を除き問題

  • 、毎回Zend_Log_Writer_Streamの_streamプロパティが消えます。
    •

私は自分のコードを生成した出力とともに添付しました。

theselinks私は他の作家Zend_Log_Writer_Databaseがアプリケーションよりも別のデータベースに書き込むため、私はそれを初期化する必要があるため、私は従っていません。今のところ私はそれをコメントアウトしています。

  • 格納されている場合はZend_Logはシリアル化されるべきではありません。
  • Zend_Cacheは、文字列のみを格納するオブジェクトを直列化する必要があるため、オプションではありません。
  • Zend_Registryは、コードのためにいくつかのシリアライゼーションが行われていたため、ヘルパークラスを使用していませんでした。それを削除すると問題が解決しました。

だから、要するに：

  • 使用なZend_RegistryなZend_Registry
に格納する際に、オブジェクト
  • をシリアライズしない保存します
