下面是总结的几个使用方法
include 'PHPExcel.php';
include 'PHPExcel/Writer/Excel2007.php';
//或者include 'PHPExcel/Writer/Excel5.php'; 用于输出.xls的
创建一个excel
$objPHPExcel = new PHPExcel();
保存excel—2007格式
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
//或者$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); 非2007格式
$objWriter->save("xxx.xlsx");
