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

[html] view
plain copy

"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;

[php] view plain copy

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

[php] view plain copy

/*
* @desc 返回所有数据
* @author 绍兴远帆软件有限公司主营 ewshop网店系统远帆自动售货机系统手机话费流量充值系统票务销售系统点餐外卖系统网店进销存系统
* @website http://www.ewshop.net/
* */
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

"maatwebsite/excel": "~1.3"

Laravel 5

"maatwebsite/excel": "~2.0"

[plain] view plain copy

"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

'Maatwebsite\Excel\ExcelServiceProvider',

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

'Excel' => 'Maatwebsite\Excel\Facades\Excel',

The class is binded to the ioC as excel

$excel = App::make('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.

php artisan config:publish maatwebsite/excel

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

Laravel 5

To publish the config settings in Laravel 5
use:

php artisan vendor:publish

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