Laravel 上使用 phpexcel的两种方式

方式1。使用原生的phpexcel ，

http://blog.csdn.net/CSwfe/article/details/52748046?locationNum=1

1、在app目录下创建一个新的文件夹，命名libs（可自定义）  app/libs/phpExcel


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）
//加入phpExcel类的路径

   "autoload": {


         "classmap": [


              "database",


               "app/libs/phpExcel"


          ],


      "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）============
 
    <span style="font-size:18px;">以下开始excel导入导出</span>  




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

public function phpexcel()
{

       //$objPHPExcel = new PHPExcel();

       //print_r($objPHPExcel);

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

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

       //print_r($query);

        if(!$query)return false;

        //Starting the PHPExcel library

        //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');

    }









     控制器中use IOFactory;   use PHPExcel_Cell;



public function ru(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($i=1;$i<count($re);$i++){

          //print_r($re);

          //echo$re[$i][1];

          $adds =DB::table('goods')->insert(['gname' => $re[$i][1], 'gprice' =>$re[$i][2]]);

       }

       //die;

       if($adds){

            echo"<script>alert('导入成功');location.href='daoru'</script>";

        }else{

            echo"<script>alert('导入失败');location.href='daoru'</script>";

        }



    }

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

 // ../  一般情况不管处于什么子目录子需要这样子即可 例如\app\Admin\Controllers\WechatMercharntPay\OrderListTodayController.php
        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

第二方法 用集成方法  maatwebsite 集成类，但是不支持一些文件。已经修复

http://blog.csdn.net/zhwxl_zyx/article/details/47251491 

并修复其中的问题 

\vendor\maatwebsite\excel\src\Maatwebsite\Excel\Readers\LaravelExcelReader.php

修改后的版本

https://github.com/yanggg1133/Laravel-Excel

增加

public function readAll()
{

    // ../  一般情况不管处于什么子目录子需要这样子即可 例如\app\Admin\Controllers\WechatMercharntPay\OrderListTodayController.php
    //include_once('../app/libs/phpexcel/phpexcel/IOFactory.php');

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


    //$this->reader =IOFactory::createReader('Excel5');

    //$this->reader->setReadDataOnly(true);

    $objPHPExcel= $this->excel;

    $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;

}

Laravel 4

Laravel 5

"require-dev": {
"fzaninotto/faker": "~1.4",
"mockery/mockery": "0.9.*",
"phpunit/phpunit": "~4.0",
"phpspec/phpspec": "~2.1",
"maatwebsite/excel": "~2.0.0"
},

添加完后执行 composer update

After updating composer, add the ServiceProvider to the providers array in app/config/app.php

You can use the facade for shorter code. Add this to your aliasses:

The class is binded to the ioC as excel

Laravel 4

Laravel Excel includes several config settings for import-, export-, view- and CSV-specific settings. Use the artisan publish command to publish the config file to your project.

The config files can now be found at app/config/packages/maatwebsite/excel

Laravel 5

To publish the config settings in Laravel 5 use:

This will add an excel.php config file to your config folder.

详细用法请参考官网 http://www.maatwebsite.nl/laravel-excel/docs/getting-started
