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：
1 <p style="margin:10px 0"><a href="export.php" class="btn">导出</a></p> 2 <form action="import.php" method="post" enctype="multipart/form-data"> 3 <div class="control-group"> 4 <label>Excel表格：</label> 5 <input type="file" name="file"/> 6 </div> 7 <div class="control-group"> 8 <input type="submit" value="导入" /> 9 </div> 10 </form>
excel导出：
1 $query = mysql_query("select * from user limit 50"); 2 $i =0; 3 $list = array(); 4 while($row=mysql_fetch_array($query)){ 5 $list[$i]['id'] = $row['id']; 6 $list[$i]['username'] = $row['username']; 7 $list[$i]['password'] = $row['password']; 8 $i++; 9 } 10 11 $title = array('ID', '邮箱', '密码'); //设置要导出excel的表头 12 exportExcel($list, '素材火用户表', $title);
exportExcel方法代码：
1 function exportExcel($data, $savefile = null, $title = null, $sheetname = 'sheet1') { 2 require_once 'PHPExcel.class.php'; 3 //若没有指定文件名则为当前时间戳 4 if (is_null($savefile)) { 5 $savefile = time(); 6 } 7 //若指字了excel表头，则把表单追加到正文内容前面去 8 if (is_array($title)) { 9 array_unshift($data, $title); 10 } 11 $objPHPExcel = new PHPExcel(); 12 //Excel内容 13 $head_num = count($data); 14 15 foreach ($data as $k => $v) { 16 $obj = $objPHPExcel->setActiveSheetIndex(0); 17 $row = $k + 1; //行 18 $nn = 0; 19 20 foreach ($v as $vv) { 21 $col = chr(65 + $nn); //列 22 $obj->setCellValue($col . $row, $vv); //列,行,值 23 $nn++; 24 } 25 } 26 //设置列头标题 27 for ($i = 0; $i < $head_num - 1; $i++) { 28 $alpha = chr(65 + $i); 29 $objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setAutoSize(true); //单元宽度自适应 30 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setName("Candara"); //设置字体 31 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setSize(12); //设置大小 32 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLACK); //设置颜色 33 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中 34 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); //垂直居中 35 $objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setBold(true); //加粗 36 } 37 38 $objPHPExcel->getActiveSheet()->setTitle($sheetname); //题目 39 $objPHPExcel->setActiveSheetIndex(0); //设置当前的sheet 40 header('Content-Type: application/vnd.ms-excel'); 41 header('Content-Disposition: attachment;filename="' . $savefile . '.xls"');//文件名称 42 header('Cache-Control: max-age=0'); 43 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); //Excel5 44 $objWriter->save('php://output'); 45 }
excel导入：
1 $tmp = $_FILES['file']['tmp_name']; 2 if (empty($tmp)) { 3 echo '请选择要导入的Excel文件！'; 4 exit; 5 } 6 7 $save_path = "uploads/"; 8 $filename = $save_path . date('Ymdhis') . ".xls"; //上传后的文件保存路径和名称 9 if (copy($tmp, $filename)) { 10 require_once 'PHPExcel.class.php'; 11 require_once 'PHPExcel/Reader/Excel5.php'; 12 13 14 $PHPReader = new PHPExcel_Reader_Excel5(); //PHPExcel_Reader_Excel2007 PHPExcel_Reader_Excel5 15 //载入文件 16 $PHPExcel = $PHPReader->load($filename); 17 18 //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 19 $currentSheet = $PHPExcel->getSheet(0); 20 //获取总列数 21 $allColumn = $currentSheet->getHighestColumn(); 22 //获取总行数 23 $allRow = $currentSheet->getHighestRow(); 24 //循环获取表中的数据，$currentRow表示当前行，从哪行开始读取数据，索引值从0开始 25 for ($currentRow = 1; $currentRow <= $allRow; $currentRow++) { 26 //从哪列开始，A表示第一列 27 for ($currentColumn = 'A'; $currentColumn <= $allColumn; $currentColumn++) { 28 //数据坐标 29 $address = $currentColumn . $currentRow; 30 //读取到的数据，保存到数组$arr中 31 $data[$currentRow][$currentColumn] = $currentSheet->getCell($address)->getValue(); 32 } 33 } 34 35 $add_time = date('Y-m-d H:i:s', time()); 36 foreach ($data as $k => $v) { 37 if ($k > 1) { 38 $sql = "insert into user (username,password) values ('" . $v['B'] . "', '" . $v['C'] . "')"; 39 40 mysql_query($sql); 41 } 42 } 43 44 $sql = "SELECT * FROM user"; 45 $result = mysql_query($sql); 46 $tip = '用户导入成功' . '，现在' . mysql_num_rows($result) . '条数据了！'; 47 echo "<script>alert('" . $tip . "');history.go(-1);</script>"; 48 exit; 49 }
