Why Email foreach does not loop?

Hi guys Why does loop

PHP Code:

<?php 
namespace App\Controllers;
use App\Models\FormModel;
use CodeIgniter\Controller;

class SendMailController extends Controller
{

    public function index() 
    {
        return view('form_view');
    }

    function sendMail() { 
        
         $email = \Config\Services::email();
        
        $to='[email protected]';
        $from = $this->request->getVar('mailTo');
        $subject = $this->request->getVar('subject');      
        $email->setTo($to);
        $email->setFrom($from, 'Booking Email');       
        $email->setSubject($subject);
        
    
        
        
        $list= array(
            'somo' => $this->request->getPost('somo'),
            'message' => $this->request->getPost('message'),/*only output this*/
       );
       
      foreach ($list as $key => $value) {
          /*not does not loop*/

        $mass = $key." : " . $value . "\n";
        
        $email->setMessage($mass);
                

      } 
      
        
        if ($email->send()) 
        {
           
           return redirect()->back()->with('success', 'Email successfully sent');

        }
        else 
        {
            $data = $email->printDebugger(['headers']);
            print_r($data);
        }
         
           $config['protocol'] = 'sendmail';
            $config['mailPath'] = '/usr/sbin/sendmail';
            $config['charset']  = 'iso-8859-1';
            $config['wordWrap'] = true;
            $config['mailtype'] = 'html';

           $email->initialize($config);
 
    }
     
      
       

} 


The output of the above code snippet does only shows:

Code:

message: blaaablaaa

and not does show:

Code:

somo: blaablaa

Where is wrong?

Codeigniter First, Codeigniter Then You!!
