ckfinder中以中文文件名上传的时候会出错，需修改下面文件：

ckfinder/core/connector/php/php*/CommandHandler/FileUpload.php

//找到这两行

if ($sFileName != $sUnsafeFileName) {
$iErrorNumber = CKFINDER_CONNECTOR_ERROR_UPLOADED_INVALID_NAME_RENAMED;
}
//在下面加这两句，很简单吧
$sExtension=CKFinder_Connector_Utils_FileSystem::getExtension($sFileName);
$sFileName=date(”Ymd”).”_”.date(”His”).”.”.$sExtension;
