PHPExcel 导入数据导多个工作区(sheet)

导出数据导EXCEL中有时需要分开保存到多个工作区内，实现代码如下：

PS：貌似只能导出总共几万条数据，并不能每个工作区都几万条。

include_once 'include/tools/arrayfunction.php';
require_once 'Classes/PHPExcel.php';
require_once 'Classes/PHPExcel/IOFactory.php';
require_once 'Classes/PHPExcel/Reader/Excel5.php';

$colmuns = array('coloumns1','coloumns2','coloumns3');
$profixs = array('A','B','C','D','E','F','G','H','I','J','L','K','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');

$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()
->setCreator("Hohan")
->setLastModifiedBy("Hohan")
->setTitle("Office 2003 XLSX Test Document")
->setSubject("Office 2003 XLSX Test Document")
->setDescription("Test document for Office 2003 XLSX, generated using PHP classes.")
->setKeywords("office 2003 openxml php")
->setCategory("Test result file");
foreach($profixs as $key => $value){

// 9-01号之前开发 最后出库日期是9-01之前或未出库 库存大于0
$sql = " ";
$sql = $dbcon->query($sql);
$sql = $dbcon->getResultArray($sql);

$objPHPExcel->createSheet();
$objActSheet = $objPHPExcel->setActiveSheetIndex($key);

$objPHPExcel->getActiveSheet()->setCellValue('A1','coloumns1');
$objPHPExcel->getActiveSheet()->setCellValue('B1','coloumns2');
$objPHPExcel->getActiveSheet()->setCellValue('C1','coloumns13');

$i = 1;
foreach($sql as $key2 => $val){

$objPHPExcel->getActiveSheet()->setCellValue('A'.($i+1),$val['coloumns1']);
$objPHPExcel->getActiveSheet()->setCellValue('B'.($i+1),$val['coloumns2']);
$objPHPExcel->getActiveSheet()->setCellValue('C'.($i+1),$val['coloumns3']);

$i ++;
}

$objPHPExcel->getActiveSheet()->setTitle($value);

}

$obwrite = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
