   function recur($d,$rek,&$aeroPole1)
  {
if(substr_count( $d, 'V:'))
  {

    $aeroPole=preg_replace('"V:"','',$d); 

    $aeroPole=explode(",",$aeroPole);

    foreach($aeroPole as $ap)
    {
          $mysqliObj3 = new mysqli('localhost','usr','pass', 'trevo');
          $comand6="SELECT * FROM `CC` WHERE name='".$ap."';";  //  name='".$RuleD[0]."';";
          $QueryObj6 = $mysqliObj3->query($comand6, MYSQLI_USE_RESULT);

          $dArea=$QueryObj6->fetch_assoc();
          $QueryObj6->close();


          if($dArea!="")
          {$rek+=1;
             $aeroPole1=array_merge($aeroPole1,recur((string)$dArea["airport_codes"],$rek,$aeroPole1));

            $fore++;

        }

    }//foreach

Answer 1

     $aeroPole1=array_unique($aeroPole1);
    return $aeroPole1;

else
{
     $aeroPole1=explode(",",$d);


  return $aeroPole1;
}

the other case if it hasn’t v:
