PHP使用PHPExcel导出，导入数据总结

导出excel:

 header("Content-type: text/html; charset=utf-8");
 include_once dirname(dirname(__FILE__)).'/Classes/PHPExcel.php';
 $objPHPExcel = new PHPExcel();
 $objPHPExcel->getProperties()->setCreator("Maarten Balliauw")
     ->setLastModifiedBy("Maarten Balliauw")
     ->setTitle("Office 2007 XLSX Test Document")
     ->setSubject("Office 2007 XLSX Test Document")
     ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.")
     ->setKeywords("office 2007 openxml php")
     ->setCategory("Test result file");

 //设置标题
 $objPHPExcel->getActiveSheet()->setTitle($filename);

 //设置表头
 $key1 = 1;
 $objPHPExcel->setActiveSheetIndex(0)
     ->setCellValue('A'.$key1, 'ID')
     ->setCellValue('B'.$key1, '关键词')
     ->setCellValue('C'.$key1, '歌曲HASH')
     ->setCellValue('D'.$key1, '歌曲名')
     ->setCellValue('E'.$key1, '排序')
     ->setCellValue('F'.$key1, '开始日期')
     ->setCellValue('G'.$key1, '结束日期')
     ->setCellValue('H'.$key1, '操作人');

 //设置样式：
 $objPHPExcel->getActiveSheet()->getStyle('A1:H1')->getFont()->setBold(true); //多个单元格
 // $objPHPExcel->getActiveSheet()->getStyle('A1:H1')->getFont()->getColor()->setARGB('FFFF0000'); //设置颜色
 // $objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setBold(true); //单个单元格
 $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);  //列宽必须单个设置
 $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(true);
 $objPHPExcel->getActiveSheet()->getColumnDimension('D')->setAutoSize(true);
 $objPHPExcel->getActiveSheet()->getColumnDimension('F')->setAutoSize(true);
 $objPHPExcel->getActiveSheet()->getColumnDimension('G')->setAutoSize(true);

 //写入内容
 foreach($datalist as $key =>$value){
     $key1=$key+2;
     $objPHPExcel->setActiveSheetIndex(0)
         ->setCellValue('A'.$key1, $value['id'])
         ->setCellValue('B'.$key1, $value['keyword'])
         ->setCellValue('C'.$key1, $value['hash'])
         ->setCellValue('D'.$key1, $value['filename'])
         ->setCellValue('E'.$key1, $value['weight'])
         ->setCellValue('F'.$key1, $value['startdate'])
         ->setCellValue('G'.$key1, $value['enddate'])
         ->setCellValue('H'.$key1, $value['editor']);
 }
 // $objPHPExcel->setActiveSheetIndex(0);

 header('Content-Type: application/vnd.ms-excel');
 header('Content-Disposition: attachment;filename="'. $filename .'.xls"');
 header('Cache-Control: max-age=0');

 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
 $objWriter->save('php://output');
 exit;

从excel导入：

 header("Content-type: text/html; charset=utf-8");
 $addFile=$_FILES['excel'];
 $excelFileName =$addFile['tmp_name'];
 $location = KG_DOMAIN . '/diysort/index';
 if ($addFile['type'] != 'application/vnd.ms-excel' && $addFile['type'] != 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet') {
     echo 'alert("上传格式错误");window.location.href="' . $location .'";';
     //header("Location: " . KG_DOMAIN . '/diysort/index');
     exit;
 }
 include_once dirname(dirname(__FILE__)).'/Classes/PHPExcel/IOFactory.php';

 $objPHPExcel = PHPExcel_IOFactory::load($excelFileName);
 $objWorksheet = $objPHPExcel->getSheet(0);
 $highestRow    = $objWorksheet->getHighestRow();          // 取得总行数
 $highestColumn = $objWorksheet->getHighestColumn();    // 取得总列数

 $highestColumnIndex = PHPExcel_Cell::columnIndexFromString ( $highestColumn );
 $excelData = array ();
 for($row = 1; $row <= $highestRow; $row++) {
     for($col = 0; $col < $highestColumnIndex; $col++) {
         $excelData[$row-1][] = $objWorksheet->getCellByColumnAndRow( $col, $row )->getValue();
     }
 }
 //数据入库
 $diysortmodule = new DiysortModule();
 $rowins = 0;
 foreach ($excelData as $key => $value) {
     if (empty($value) || trim($value[0]) == '关键词' || trim($value[0] == 'ID')) {
         continue;
     }
     $keyword = trim(addslashes($value[0]));
     $hash = trim(addslashes($value[1]));
     $filename = trim(addslashes($value[2]));
     $weight = intval($value[3]);
     $startdate = trim(addslashes($value[4]));
     $enddate = trim(addslashes($value[5]));
     $adddate = date('Y-m-d H:i:s',time());
     $input_data = array(
         'keyword'    => $keyword,
         'startdate'  => $startdate,
         'enddate'    => $enddate,
         'hash'       => $hash,
         'filename'   => $filename,
         'weight'     => $weight,
         'adddate'    => $adddate,
         'editor'     => $this->editor,
     );
     if (!empty($hash) && !empty($filename) && is_numeric($weight)) {
         $newid = $diysortmodule->addData($input_data);
         if ($newid > 0) {
             $rowins ++;
         }
     }
 }
 echo 'alert("共上传成功'. $rowins.' 条记录");window.location.href="' . $location .'";';
 exit;
