如何每30条记录放置换行符

Question

我有一个程序通过PHPExcel将MySQL数据写入Excel并且我没有错误，但问题是他们没有每30条记录中有任何换行符。

如何在PHPExcel中以编程方式实现此目的？

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();
}

Answer 1

如果您指的是电子表格的每30行，请按照in the documentation所述使用打印设置选项：

$objPHPExcel->getActiveSheet()
    ->setBreak('A10' , PHPExcel_Worksheet::BREAK_ROW);

将在第10行设置打印中断

因此，只需在构建工作表

时每隔30行设置这些断点即可

Answer 2

如果您想准确控制换行的位置，则只需使用 \ n 。

示例：

$objPHPExcel->getActiveSheet()->setCellValue('H5', "Hello\nWorld");

在PHP字符串中添加转义序列时，应始终使用双引号。
