原生PHP网页导出和导入excel文件实例

原生PHP实现的网页导出和导入excel文件实例，包括上传也是用的原生。还可在exportExcel方法里设置字体等表格样式。

导出和导入表单代码：

 <p style="margin:10px 0"><a href="export.php" class="btn">导出</a></p>
 <form action="import.php" method="post" enctype="multipart/form-data">
     <div class="control-group">
         <label>Excel表格：</label>
         <input type="file"  name="file"/>
     </div>
     <div class="control-group">
         <input type="submit"  value="导入" />
     </div>
 </form>

excel导出：

 $query = mysql_query("select * from user limit 50");
 $i =0;
 $list = array();
 while($row=mysql_fetch_array($query)){
     $list[$i]['id'] = $row['id'];
     $list[$i]['username'] = $row['username'];
     $list[$i]['password'] = $row['password'];
     $i++;
 }  

 $title = array('ID', '邮箱', '密码'); //设置要导出excel的表头
 exportExcel($list, '素材火用户表', $title);

exportExcel方法代码：

 function exportExcel($data, $savefile = null, $title = null, $sheetname = 'sheet1') {
     require_once 'PHPExcel.class.php';
     //若没有指定文件名则为当前时间戳
     if (is_null($savefile)) {
         $savefile = time();
     }
     //若指字了excel表头，则把表单追加到正文内容前面去
     if (is_array($title)) {
         array_unshift($data, $title);
     }
     $objPHPExcel = new PHPExcel();
     //Excel内容
     $head_num = count($data); 

     foreach ($data as $k => $v) {
         $obj = $objPHPExcel->setActiveSheetIndex(0);
         $row = $k + 1; //行
         $nn = 0; 

         foreach ($v as $vv) {
             $col = chr(65 + $nn); //列
             $obj->setCellValue($col . $row, $vv); //列,行,值
             $nn++;
         }
     }
     //设置列头标题
     for ($i = 0; $i < $head_num - 1; $i++) {
         $alpha = chr(65 + $i);
         $objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setAutoSize(true); //单元宽度自适应
         $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setName("Candara");  //设置字体
         $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setSize(12);  //设置大小
         $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLACK); //设置颜色
         $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中
         $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); //垂直居中
         $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setBold(true); //加粗
     } 

     $objPHPExcel->getActiveSheet()->setTitle($sheetname); //题目
     $objPHPExcel->setActiveSheetIndex(0); //设置当前的sheet
     header('Content-Type: application/vnd.ms-excel');
     header('Content-Disposition: attachment;filename="' . $savefile . '.xls"');//文件名称
     header('Cache-Control: max-age=0');
     $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); //Excel5
     $objWriter->save('php://output');
 }

excel导入：

 $tmp = $_FILES['file']['tmp_name'];
 if (empty($tmp)) {
     echo '请选择要导入的Excel文件！';
     exit;
 } 

 $save_path = "uploads/";
 $filename = $save_path . date('Ymdhis') . ".xls"; //上传后的文件保存路径和名称
 if (copy($tmp, $filename)) {
     require_once 'PHPExcel.class.php';
     require_once 'PHPExcel/Reader/Excel5.php'; 

     $PHPReader = new PHPExcel_Reader_Excel5(); //PHPExcel_Reader_Excel2007 PHPExcel_Reader_Excel5
     //载入文件
     $PHPExcel = $PHPReader->load($filename); 

     //获取表中的第一个工作表，如果要获取第二个，把0改为1，依次类推
     $currentSheet = $PHPExcel->getSheet(0);
     //获取总列数
     $allColumn = $currentSheet->getHighestColumn();
     //获取总行数
     $allRow = $currentSheet->getHighestRow();
     //循环获取表中的数据，$currentRow表示当前行，从哪行开始读取数据，索引值从0开始
     for ($currentRow = 1; $currentRow <= $allRow; $currentRow++) {
         //从哪列开始，A表示第一列
         for ($currentColumn = 'A'; $currentColumn <= $allColumn; $currentColumn++) {
             //数据坐标
             $address = $currentColumn . $currentRow;
             //读取到的数据，保存到数组$arr中
             $data[$currentRow][$currentColumn] = $currentSheet->getCell($address)->getValue();
         }
     } 

     $add_time = date('Y-m-d H:i:s', time());
     foreach ($data as $k => $v) {
         if ($k > 1) {
             $sql = "insert into user (username,password) values ('" . $v['B'] . "', '" . $v['C'] . "')"; 

             mysql_query($sql);
         }
     } 

     $sql = "SELECT * FROM user";
     $result = mysql_query($sql);
     $tip = '用户导入成功' . '，现在' . mysql_num_rows($result) . '条数据了！';
     echo "<script>alert('" . $tip . "');history.go(-1);</script>";
     exit;
 }
