'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'); }

$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) .
