How to display the array element to view

Question

I have a problem regarding the return view('doctor_index', compact('result') on my contoller

here is my controller

public function index()
{

    $data = Auth::user()->patient;

    $data = explode(',', $data);

    foreach ($data as $key => $datas) {

       $result = DB::table('patients')->where('id', $datas)->get();

            foreach ($result as $key => $res) {

                $output = ' <h4><b>'. $res->patient_name .'</b></h4>
                                </p>Birthday: <strong>'. $res->post_date .'</strong>  Age: <strong>'. $res->patients_age .'</strong></p>
                                <p>Address: <strong>'. $res->patient_address .'</strong></p><br><br>';
            }  

         echo $output;

        // return view('doctor_index', compact('output'));
    }
}

at first i used echo $output; this is what it displayed

Output of echo $output:

Now if i use the return view on the controller it displays

Output of the return view:

as you can see when i use the return view it only display the first element

My question is how can i display all of the elements to my view using the return view

my view code:

<div class="col-md-8 col-md-offset-2">
        <div class="panel panel-default">
            <div class="panel-body">

                <div class="col-md-12">
                    <h2><b>{{ Auth::user()->name }} </b></h2>
                      <p>Email: <strong> {{ Auth::user()->email }} </strong></p> 
                </div>
            </div>
        </div>

        <div class="panel panel-default">
            <div class="panel-body">

                <div class="col-md-12">
                    <h3>Patients</h3>
                </div>
                <div class="col-md-12">
                    <div class="container">

                           <?php echo $output ?>
                    </div>
                </div>
            </div>
        </div>
    </div>

Answer 1

With functions and methods once it reaches the return statement it won't continue through the other loops. Instead you should pass the array to the view and loop over the array within your view. So your controller would look something like this:

public function index()
{

    $data = Auth::user()->patient;

    $data = explode(',', $data);
    $responseData = [];

    foreach ($data as $key => $datas) {

       $result = DB::table('patients')->where('id', $datas)->get();

            foreach ($result as $key => $res) {

                $responseData[] = ' <h4><b>'. $res->patient_name .'</b></h4>
                                </p>Birthday: <strong>'. $res->post_date .'</strong>  Age: <strong>'. $res->patients_age .'</strong></p>
                                <p>Address: <strong>'. $res->patient_address .'</strong></p><br><br>';
            }  
    }

    return view('doctor_index', compact('responseData'))
}

And then your blade template would look something like this.

<div class="col-md-8 col-md-offset-2">
        <div class="panel panel-default">
            <div class="panel-body">

                <div class="col-md-12">
                    <h2><b>{{ Auth::user()->name }} </b></h2>
                      <p>Email: <strong> {{ Auth::user()->email }} </strong></p> 
                </div>
            </div>
        </div>

        <div class="panel panel-default">
            <div class="panel-body">

                <div class="col-md-12">
                    <h3>Patients</h3>
                </div>
                <div class="col-md-12">
                    <div class="container">
                           @foreach($responseData as $output)
                               {!! $output !!}
                           @endforeach
                    </div>
                </div>
            </div>
        </div>
    </div>
