示例1: fetchFileMetadata
/**
* Helper function: do the actual database query to fetch file metadata.
*
* @param string $key key
* @param $readFromDB: constant (default: DB_SLAVE)
* @return boolean
*/

} else {

}示例2: getChunkStatus
/**
* Get the chunk db state and populate update relevant local values

}示例3: removeFileNoAuth
/**
* Remove a file (see removeFile), but doesn't check ownership first.
*
* @return boolean: success
*/
public function removeFileNoAuth($key)
