PHP导入导出

 

        

导入Excel表：

           

html代码

第二，在对应的php文件进行文件的处理

复制代码 代码如下:

 if (! empty ( $_FILES ['file_stu'] ['name'] ))

 {
    $tmp_file = $_FILES ['file_stu'] ['tmp_name'];
    $file_types = explode ( ".", $_FILES ['file_stu'] ['name'] );
    $file_type = $file_types [count ( $file_types ) - 1];

    
     if (strtolower ( $file_type ) != "xls")             
    {
          $this->error ( '不是Excel文件，重新上传' );
     }

   
     $savePath = SITE_PATH . '/public/upfile/Excel/';

   
     $str = date ( 'Ymdhis' );
     $file_name = $str . "." . $file_type;

    
     if (! copy ( $tmp_file, $savePath . $file_name ))
      {
          $this->error ( '上传失败' );
      }

   
  $res = Service ( 'ExcelToArray' )->read ( $savePath . $file_name );

  
   //spl_autoload_register ( array ('Think', 'autoload' ) );

  
   foreach ( $res as $k => $v )
   {
       if ($k != 0)
      {
           $data ['uid'] = $v [0];
           $data ['password'] = sha1 ( '111111' );
           $data ['email'] = $v [1];

           $data ['uname'] = $v [3];

          $data ['institute'] = $v [4];
         $result = M ( 'user' )->add ( $data );
         if (! $result)
         {
              $this->error ( '导入数据库失败' );
          }
      }
   }

}

第三：ExcelToArrary类,用来引用phpExcel并处理Excel数据的

复制代码 代码如下:

class ExcelToArrary extends Service{

 public function __construct() {

    
     include_once('./Excel/PHPExcel.php');
 }

public function read($filename,$encode='utf-8'){

          $objReader = PHPExcel_IOFactory::createReader('Excel5');

          $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;

    }    

 }

第四，以上就是导入的全部内容，phpExcel包附在最后。

（二）Excel的导出（相对于导入简单多了）

第一，先查出数据库里面要生成Excel的数据，如：

$data= M('User')->findAll();   //查出数据
$name='Excelfile';    //生成的Excel文件文件名
$res=service('ExcelToArrary')->push($data,$name);

第二，ExcelToArrary类,用来引用phpExcel并处理数据的   

复制代码 代码如下:

class ExcelToArrary extends Service{

       public function __construct() {

             
               include_once('./Excel/PHPExcel.php');
       }

    
    public function push($data,$name='Excel'){

          error_reporting(E_ALL);
          date_default_timezone_set('Europe/London');
         $objPHPExcel = new PHPExcel();

       
         $objPHPExcel->getProperties()->setCreator("转弯的阳光")
                               ->setLastModifiedBy("转弯的阳光")
                               ->setTitle("数据EXCEL导出")
                               ->setSubject("数据EXCEL导出")
                               ->setDescription("备份数据")
                               ->setKeywords("excel")
                              ->setCategory("result file");
        
        foreach($data as $k => $v){

             $num=$k+1;
             $objPHPExcel->setActiveSheetIndex(0)

                         //Excel的第A列，uid是你查出数组的键值，下面以此类推
                          ->setCellValue('A'.$num, $v['uid'])   
                          ->setCellValue('B'.$num, $v['email'])
                          ->setCellValue('C'.$num, $v['password'])
            }

            $objPHPExcel->getActiveSheet()->setTitle('User');
            $objPHPExcel->setActiveSheetIndex(0);
             header('Content-Type: application/vnd.ms-excel');
             header('Content-Disposition: attachment;filename="'.$name.'.xls"');
             header('Cache-Control: max-age=0');
             $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
             $objWriter->save('php://output');
             exit;
      }
