PHPExcel导出数据的基本使用方法

<?php
//引入excel文件
include "Phpexcel/Phpexcel.php";
include "Phpexcel/Phpexcel/Writer/Excel2007.php";
//实例化对象
$objExcel = new PHPExcel();
//获得当前sheet操作对象
$objSheet = $objExcel->getActiveSheet();
//设置sheet名称
$objSheet->setTitle('mysheet');
//填充数据 一
/*$objSheet->setCellValue('A1','ID')
   ->setCellValue('B1','班级')
   ->setCellValue('C1','姓名')
   ->setCellValue('D1','性别')
   ->setCellValue('E1','分数');
$objSheet->setCellValue('A2','1')
   ->setCellValue('B2','一班')
   ->setCellValue('C2','james')
   ->setCellValue('D2','男')
   ->setCellValue('E2','60');
$objSheet->setCellValue('A3','2')
   ->setCellValue('B3','二班')
   ->setCellValue('C3','Mares')
   ->setCellValue('D3','女')
   ->setCellValue('E3','70');
$objSheet->setCellValue('A4','3')
   ->setCellValue('B4','三班')
   ->setCellValue('C4','mariros')
   ->setCellValue('D4','男')
   ->setCellValue('E4','80');*/
//填充数据 数组形式
$excelArr = array(
   array('ID','班级','姓名','性别','分数'),
   array('1','一班','高飞','男','60'),
   array('2','二班','乔丹','男','50'),
   array('3','三班','布莱尔','女','40'),
   array('4','四班','大卫','男','30'),
);
$objSheet->fromArray($excelArr);
//写入数据
$objWriter = PHPExcel_IOFactory::createWriter($objExcel,'Excel2007');
//保存数据
$objWriter->save('myexcel2.xlsx');
