為現有應用程式啟用錯誤處理時,請考慮將 IsBlank 取代為 IsBlankOrError 以保留現有應用程式行為。 在新增錯誤處理之前,空白值用於表示來自資料庫與錯誤值的 Null 值。 錯誤處理會將這兩個空白的解釋分開,這可能會變更繼續使用 IsBlank 的現有應用程式的行為。IsBlank 的傳回值是布林值 True 或False。

Edit: Could it be this setting?'logs' => array( 'file' => null, ), I can't find any documentation on what that's supposed to be set to. Is that supposed to contain the name of a log file to write or log file(s) to watch? If the latter, can it be an array?
