thinkphp 结合phpexcel实现excel导入

控制器文件：

 class ExcelAction extends Action {
     public function __construct()
     {
         import('ORG.Util.ExcelToArrary');//导入excelToArray类
     }

     public function index()
     {
         $this->display();
     }
     public function add()
     {
         $tmp_file = $_FILES ['file_stu'] ['tmp_name'];
         $file_types = explode ( ".", $_FILES ['file_stu'] ['name'] );
         $file_type = $file_types [count ( $file_types ) - ];

          /*判别是不是.xls文件，判别是不是excel文件*/
          if (strtolower ( $file_type ) != "xlsx" && strtolower ( $file_type ) != "xls")
          {
               $this->error ( '不是Excel文件，重新上传' );
          }

          /*设置上传路径*/
          $savePath = C('UPLOAD_DIR');

          /*以时间来命名上传的文件*/
          $str = date ( 'Ymdhis' );
          $file_name = $str . "." . $file_type;

          /*是否上传成功*/
          if (! copy ( $tmp_file, $savePath . $file_name ))
           {
               $this->error ( '上传失败' );
           }
         $ExcelToArrary=new ExcelToArrary();//实例化
         $res=$ExcelToArrary->read(C('UPLOAD_DIR').$file_name,"UTF-8",$file_type);//传参,判断office2007还是office2003

         foreach ( $res as $k => $v ) //循环excel表
            {
                $k=$k-;//addAll方法要求数组必须有0索引
                $data[$k]['name1'] = $v [];//创建二维数组
                $data[$k]['name2'] = $v [];
                $data[$k]['name3'] = $v [];
                $data[$k]['name4'] = $v [];
           }
           $kucun=M('kucun');//M方法
           $result=$kucun->addAll($data);
           if(! $result)
           {
               $this->error('导入数据库失败');
               exit();
           }
           else
           {
               $this->success ( '导入成功' );
           }
     }

定义Excel转换数组类：

 class ExcelToArrary {
   public function __construct() {
         Vendor("Excel.PHPExcel");//引入phpexcel类(注意你自己的路径)
         Vendor("Excel.PHPExcel.IOFactory");
   }
   public function read($filename,$encode,$file_type){
             if(strtolower ( $file_type )=='xls')//判断excel表类型为2003还是2007
             {
                 Vendor("Excel.PHPExcel.Reader.Excel5");
                 $objReader = PHPExcel_IOFactory::createReader('Excel5');
             }elseif(strtolower ( $file_type )=='xlsx')
             {
                 Vendor("Excel.PHPExcel.Reader.Excel2007");
                 $objReader = PHPExcel_IOFactory::createReader('Excel2007');
             }
             $objReader->setReadDataOnly(true);
             $objPHPExcel = $objReader->load($filename);
             $objWorksheet = $objPHPExcel->getActiveSheet();
             $highestRow = $objWorksheet->getHighestRow();
             $highestColumn = $objWorksheet->getHighestColumn();
             $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
             $excelData = array();
             for ($row = 1; $row <= $highestRow; $row++) {
                 for ($col = 0; $col < $highestColumnIndex; $col++) {
                     $excelData[$row][] =(string)$objWorksheet->getCellByColumnAndRow($col, $row)->getValue();
                     }
             }
             return $excelData;
       }

前台导入页面：

 <form method="post" action="Excel/add" enctype="multipart/form-data">
          <h3>导入Excel表：</h3><input  type="file" name="file_stu" />

            <input type="submit"  value="导入" />
 </form>

注意:在php.ini里面把;extension=php_zip.dll前面的分号去掉；

C('UPLOAD_DIR').$file_name是上传的excel的路径；
