laravel框架实现phpExcel导入导出

laravel框架实现phpExcel导入导出，首先必须在laravel引入第三方类

1、在app目录下创建一个新的文件夹，命名libs（可自定义）

2、（可选）考虑到后面可能会引用很多库，so，在libs下再创建一个phpExcel文件夹,把phpExcel类放入此文件夹下。

3、找到根目录下的composer.json文件

4、找到composer.json中定义的（看我备注）

           "autoload": {  

                 "classmap": [  

                      "database",  

                     "app/libs/phpExcel"  //加入phpExcel类的路径 

                  ],  

              "psr-4": {  

                    "App\\": "app/"  

               }

        },

5、安装composer，windows下可以在百度上下载

6、运行命令行进入项目根目录，执行“composer dumpautoload”，

7、在控制器中use PHPExcel

8、在方法中实例化phpExccel对象，打印该对象看phpExcel类是否引入成功。

     $objPHPExcel = new PHPExcel();

     print_r($objPHPExcel);

==========以上是引入phpExcel类步骤（其它第三方类与此类似）============

以下开始excel导入导出

//导出     控制器中use PHPExcel;  use IOFactory;

publicfunction phpexcel()
{

       //$objPHPExcel = new PHPExcel();

       //print_r($objPHPExcel);

        $query =DB::table('goods')->get();

        //$query =$this ->db->query($sql);

       //print_r($query);

        if(!$query)return false;

        //StartingthePHPExcellibrary

        //加载PHPExcel类

       //$this->load->library('PHPExcel');

        //$this->load ->library('PHPExcel/IOFactory');

        $objPHPExcel= new PHPExcel();

        include_once('../app/libs/phpexcel/phpexcel/IOFactory.php');

        $objPHPExcel->getProperties()-> setTitle("export") ->setDescription("none");

        $objPHPExcel-> setActiveSheetIndex(0);

        //Fieldnamesinthefirstrow

        $fields = DB::select("select COLUMN_NAME from information_schema.COLUMNS where

           table_name = 'goods';");

       //print_r($fields);die;

        $col = 0;

       foreach($fields as $field){

            $field =$field['COLUMN_NAME'];

            $objPHPExcel-> getActiveSheet() -> setCellValueByColumnAndRow($col, 1,$field);

            $col++;

        }

       // die;
       //Fetchingthetabledata

       $row = 2;

        foreach($query as $data)
        {

             $col =0;

             foreach($fields $field)

             {

                 //print_r($data);

                 $field =$field['COLUMN_NAME'];

                 $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col,$row,!empty($data["$field"])?$data["$field"]:'');

                 $col++;

             }

            $row++;

        }

        //die;

        $objPHPExcel-> setActiveSheetIndex(0);

        $objWriter =IOFactory :: createWriter($objPHPExcel, 'Excel5');

        //Sendingheaderstoforcetheusertodownloadthefile

        header('Content-Type:application/vnd.ms-excel');

       //header('Content-Disposition:attachment;filename="Products_' .date('dMy') . '.xls"');

        header('Content-Disposition:attachment;filename="Brand_' .date('Y-m-d') . '.xls"');

        header('Cache-Control:max-age=0');

        $objWriter-> save('php://output');

    }

 

//导入     控制器中use IOFactory;   use PHPExcel_Cell;

public functionru(Request $request){
       $tmp_file =$_FILES ['file_stu'] ['tmp_name'];

       $file_types =explode ( ".", $_FILES ['file_stu'] ['name'] );

       $file_type =$file_types [count ( $file_types ) - 1];

       /*判别是不是.xls文件，判别是不是excel文件*/

       if (strtolower( $file_type ) != "xls"){

          $this->error ( '不是Excel文件，重新上传' );

       }

       $savePath ="./excel/";

       /*以时间来命名上传的文件*/

       $str =date('Ymdhis');

       $file_name =$str . "." . $file_type;

       //echo$file_name;die;

       $request->file('file_stu')->move($savePath, $file_name);

       /*是否上传成功*/

       /*if(!copy($tmp_file,$savePath.$file_name)){

          $this->error ( '上传失败' );

       }*/

       //要获得新的文件路径+名字

       $fullpath =$savePath.$file_name;

       //echo$fullpath;die;

       $re =$this->read($fullpath,'utf-8');

       //print_r($re);die;

       for($i=1;$iinsert(['gname' => $re[$i][1], 'gprice' =>$re[$i][2]]);

       }

       //die;

       if($adds){

            echo"";

        }else{

            echo"";

        }

 

    }

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

        include_once('../app/libs/phpexcel/phpexcel/IOFactory.php');

        //$this->load ->library('PHPExcel/IOFactory');

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

        $objReader->setReadDataOnly(true);

        $objPHPExcel= $objReader->load($filename);

        $objWorksheet= $objPHPExcel->getActiveSheet();

        $highestRow =$objWorksheet->getHighestRow();

        //echo$highestRow;die;

        $highestColumn = $objWorksheet->getHighestColumn();

        //echo$highestColumn;die;

        $highestColumnIndex =PHPExcel_Cell::columnIndexFromString($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;

}

phpExcel导入导出终于完成了，赶快尝试一下吧！
