利用PHPExcel实现数据保存到excel文件

    include(dirname(__FILE__) .'/phpexcel-1.7.7/Classes/PHPExcel.php');
    include(dirname(__FILE__) .'/phpexcel-1.7.7/Classes/PHPExcel/IOFactory.php');


    $header_arr = array('A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
    $objPHPExcel = new PHPExcel();//实例化一个要保存的phpExcel对象

//写数据开始

    //在激活的工作区写入数据 (单条写入数据演示)
    $objPHPExcel->getActiveSheet()->setCellValue('B8', '汉字');

    //在激活的工作区写入数据 (数组写入数据演示)
    $startRow = 1;
    foreach ($list as $row) {
        foreach ($indexKey as $key => $value){
            //这里是设置单元格的内容
            $objActSheet->setCellValue($header_arr[$key].$startRow,$row[$value]);
        }
        $startRow++;
    }


//写数据结束

    $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
    $objWriter->save($file);
