php laravel 5.1 使用excel 插件實現導入導出

1、數據庫如下：

2、前台頁面：

<form action="/excel/import" method='post' enctype="multipart/form-data">
    <input type="hidden" name="_token" value="{{ csrf_token() }}" />
    <input id="fileId1" type="file" accept="application/vnd.ms-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" name="file"/>
    <input type="submit" value="確認">
</form>
3、路由：

Route::get('admin/exceladd','admin\ExcelController@index');
Route::get('excel/export','admin\ExcelController@export');
Route::post('excel/import','admin\ExcelController@import');
4、controller：

public  function export(){
    $student = DB::table('student')->get();
    $student =json_encode($student,true);
    $student =json_decode($student,true);
    Array_unshift($student,['id','申請人','申請產品名稱','申請理由','聯系人1','聯系人2','聯系人3']);
    Excel::create(iconv('UTF-8', 'GBK', '學生成績').date('Y-m-d-H-i-s'),function($excel) use ($student){
        $excel->sheet('score', function($sheet) use ($student){
            $sheet->rows($student);
        });
    })->store('xls')->export('xls');
}

public  function  import(Request $request)
{
    $file = $request->file('file');
    $originalName = $file->getClientOriginalName(); // 文件原名
    $ext = $file->getClientOriginalExtension();     // 擴展名
    $realPath = $file->getRealPath();   //臨時文件的絕對路徑
    $type = $file->getClientMimeType();
    $filename = date('Y-m-d-H-i-s') . '-' . uniqid() . '.' . $ext;
    $bool = Storage::disk('uploads')->put($filename, file_get_contents($realPath));
    $filePath = 'storage/app/uploads/'.iconv('UTF-8', 'GBK', $filename);
    Excel::load($filePath,function ($reader){
        $reader = $reader->getSheet(0);
        $data = $reader->toArray();
       for($i=1;$i<count($data);$i++){
                $student = array(
                    'num'=>$data[$i][0],
                    'name'=>$data[$i][1],
                    'score'=>$data[$i][2],
                    'remark'=>$data[$i][3],
                );
                $res=Student::forceCreate($student);
               echo '成功';
       }
    });

}
記得引入命名空間和modle
