【问题描述】：

我的控制器函数中有变量getscore？

 public   function questionquiz5(Request $request){


           static $getscore=0;

     $getidvalue = Input::get('getid');
     $getanswervalue = Input::get('getanswer');

     $dbscore = \DB::table('5question')->select('question_id','correct_answer','question_marks')->
     where('question_id','=',$getidvalue)->get();

   foreach ($dbscore as $value) {

       if ( $getanswervalue==($value->correct_answer) ){

                       $this->getscore  =  $this->getscore + $value->question_marks;           

          }elseif($getanswervalue == null){

                       $emptyvalue = -1;
                       $this->getscore += $emptyvalue;

          }else{

                       $novalue=0;
                       $this->getscore += $novalue;               
          }

    }
          echo "$this->getscore";


       Session::push('getscoresession',$this->getscore);


    $getsession = [  'qid' => $getidvalue,  'answer' => $getanswervalue];

       Session::push('answer', $getsession);

    return response()->json(['qid'=>$getidvalue,'answer'=>$getanswervalue]);

}

我想增加我的getscore 值，我应用foreach 循环但不工作....因为我认为它总是重置为零？如何让它发生，所以当我运行循环时，我的getscore值添加并存储在会话中？

标签： php laravel session foreach

【解决方案1】：

将变量放入会话

session('name', 'value');

或者

$request->session()->('name', 'value');

检索会话

session('name');

在foreach循环中添加变量

$name = session('name');

foreach($things as $thing){
    $name += $thing
}

在 foreach 之后更新会话值

$request->session()->put('name', 'value')

或者

session('name', 'value');
