hashing password and decrypting(need hlp)

@InsiteFX and @qury
He wants to verify it and login a person. Not decrypt the password; It's just a bad choice of words.

PHP Code:

public function login_model($email,$password)
  {
   
      $this->db->select('*');
      $this->db->from('users');
      $this->db->where('Email',$email);
      $this->db->where('Role_Id !=',1);
      $query = $this->db->get();

      if($query->num_rows() === 1)
      {
          // storing the results in the variable $data
          $data = $query->row(); 

            if($this->verifyHash($password,$data->password) === TRUE)
            {
                $dat = array(
                   'id_user' => $data->id_User,
                   'FirstName' => $data->FirstName,
                   'LastName' => $data->LastName,
                   'Phonenumber' => $data->PhoneNo,                  
                   'Email' => $data->Email,
                   'role' => $data->Role_Id,
                   'imageUrl' => $data->imageUrl,
                   'category_id' => $data->category_id,
                   'IdType' => $data->IdType,
                   'IdNumber' => $data->IdNumber,
                   'DOB' => $data->DOB,
                   'confirmCode' => $data->confirmCode,
                   'confirmed' => $data->confirmed,
                   'Points'=> $data->Points                  
                );
            }
           
            $this->session->set_userdata($dat); 
            return true;     
      }
      else{
          return false;
       }
      
  }
