    $extension = pathinfo($photo1, PATHINFO_EXTENSION);
    if(in_array($extension,$allow)){
      $target_path = "uploads/";
      $photo1 = md5(rand() * time()).'.'.$extension;
      $target_path = $target_path . $photo1;
      move_uploaded_file($_FILES['photo1']['tmp_name'], $target_path);
      $photo_one = ($photo1!='')?" reg_st_photo='$photo1' ". ',':'';
