Show all.
1，异常处理

$o_flashMessage = t3lib_div::makeInstance(
                        't3lib_FlashMessage',
                        $GLOBALS['LANG']->getLL('function1.file_upload_success', true),
                        'Info',
                        t3lib_FlashMessage::OK
                );
                                t3lib_FlashMessageQueue::addMessage($o_flashMessage);
                $content .= t3lib_FlashMessageQueue::renderFlashMessages();

2，使用typo3后台自带的选项卡

$menus = array();
                        if($rowsForCreate){
                                $menus[] = array(
                                        'label' => 'Create Records',
                                        'content' => $thead.$rowsForCreate.$tfoot
                                );
                        }
                        if($rowsForOverride){
                                $menus[] = array(
                                        'label' => 'Override Records',
                                        'content' => $thead.$rowsForOverride.$tfoot
                                );
                        }
                        if($rowsForDelete){
                                $menus[] = array(
                                        'label' => 'Delete Records',
                                        'content' => $thead.$rowsForDelete.$tfoot
                                );
                        }
                        if($rowsForKeep){
                                $menus[] = array(
                                        'label' => 'Keep Records',
                                        'content' => $thead.$rowsForKeep.$tfoot
                                );
                        }
                        if(empty($menus))throw new Exception("Nothing need to be change. Records in database are the same as in the csv file.", 1);
                        $content .= $this->doc->getDynTabMenu($menus, 'records_tabs');        

3，使用表格样式，只要class一样就自动有了样式

$thead = ''.
                                ''.
                                ''.
                                ''.
                                ''.
                                ''.
                                ''.
                                ''.
                                ''.
                                ''.
                                ''
                        ;
4，使用树状结构展示数组
t3lib_div::naturalKeySortRecursive($baseData);
                        $arrayBrowser = t3lib_div::makeInstance('t3lib_arrayBrowser');
                        $arrayBrowser->varName = 'TesterUnitData';
                        $arrayBrowser->expAll = TRUE;
                        $arrayBrowser->dontLinkVar = TRUE;
                        $tree = $arrayBrowser->tree($baseData, '', '');
                        $label = 'TesterUnitData';
                        $content.= '

';
                        $content.= '

                                                
' . $label . '
                                        
                                        

                                                
' . $tree . '
                                        
                                
                        ';
                        
                        $content .= '
