如何把每30个logging的换行符
我有一个程序，通过PHPExcel写入MySQL数据到Excel，我没有错误，但问题是他们没有任何换行符的每30条logging。
我如何在PHPExcel中以编程方式实现这个function？
这是我的代码：
require 'PHPExcel.php'; require 'PHPExcel/Writer/Excel2007.php'; require 'PHPExcel/IOFactory.php'; $user = "root"; $pass = "admin"; $host = "localhost"; $db = "hrtms"; $dept = "WAREHOUSE/DRIVER"; $TimeIn = ""; $LunchOut = ""; $LunchIn = ""; $TimeOut = ""; $objPHPExcel = new PHPExcel(); try{ $con = new PDO("mysql:host=$host;dbname=$db",$user,$pass); $con->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION); $con->exec('SET NAMES "utf8"'); } catch(PDOException $e){ echo $e->getMessage(); exit(); } try{ $query = $con->prepare("SELECT * FROM emptb WHERE Department = :dept ORDER BY id ASC"); $query->bindParam(':dept',$dept); $query->execute(); } catch(PDOException $e){ echo $e->getMessage(); exit(); } $objPHPExcel->setActiveSheetIndex(0); //set default font $objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setName('Verdana'); //set titles $objPHPExcel->getActiveSheet()->SetCellValue('B1','EMPLOYEE ATTENDANCE LOGS'); //$objPHPExcel->getActiveSheet()->getStyle('B1')->getAlignment()->setWrapText(true); //merge cells $objPHPExcel->getActiveSheet()->mergeCells('B1:T1');

header('Cache-Control:max-age=0'); $excelWriter->save('php://output'); 如果您是指电子表格的每30行，请按照文档中的说明使用打印设置选项：
$objPHPExcel->getActiveSheet() ->setBreak('A10' , PHPExcel_Worksheet::BREAK_ROW);
将在第10行设置打印中断
所以，只要在构build工作表的时候每30行设置一次断点
您只需要使用\ n如果您想要精确控制行换行的位置。
例：
$objPHPExcel->getActiveSheet()->setCellValue('H5', "Hello\nWorld");
在PHPstring中添加转义序列时，应始终使用双引号。
