Run nested loop to transfer data into an array, wordpress, ACF

I’m having a problem with a multidimensional array. Specifically, I have multiple nested loops that take data from ACF. I want the data of these loops to be saved as a multidimensional array. Specifically this is my code:

 <?php
$array_save=array();
if( have_rows('dtkpxd', 'option') ):
  while( have_rows('dtkpxd', 'option') ): the_row();
    //Begin dtkpxd
    if( have_rows('lnxd') ):
      while( have_rows('lnxd') ) : the_row();
        // Begin lnxd
        $tlnxd=get_sub_field('name_ln');
        if( have_rows('goth') ):
          while( have_rows('goth') ) : the_row();
            //   Begin goth      
            if( have_rows('gr_goth_1') ):
              while( have_rows('gr_goth_1') ) : the_row();
                $name_goth_1=get_sub_field('name_goth');
                if( have_rows('gr_gogia') ):
                  while( have_rows('gr_gogia') ) : the_row();
                    $name_gogia_xd_1_1=get_sub_field('gogia_1');
                    $pri_xd_1_1=get_sub_field('gigoi_1');
                    $name_gogia_xd_1_2=get_sub_field('gogia_2');
                    $pri_xd_1_2=get_sub_field('gigoi_2');
                    $name_gogia_xd_1_3=get_sub_field('gogia_3');
                    $pri_xd_1_3=get_sub_field('gigoi_3');
                    $name_gogia_xd_1_4=get_sub_field('gogia_4');
                    $pri_xd_1_4=get_sub_field('gigoi_4');                   
                  endwhile;
                endif;
              endwhile;
            endif;
            //end gr_goth_1
            if( have_rows('gr_goth_2') ):
              while( have_rows('gr_goth_2') ) : the_row();
                $name_goth_2=get_sub_field('name_goth');
                if( have_rows('gr_gogia') ):
                  while( have_rows('gr_gogia') ) : the_row();
                    $name_gogia_xd_2_1=get_sub_field('gogia_1');
                    $pri_xd_2_1=get_sub_field('gigoi_1');

                    $name_gogia_xd_2_3=get_sub_field('gogia_3');
                    $pri_xd_2_3=get_sub_field('gigoi_3');
                    $name_gogia_xd_2_4=get_sub_field('gogia_4');
                    $pri_xd_2_4=get_sub_field('gigoi_4');                   
                  endwhile;
                endif;
              endwhile;
            endif;
            //end gr_goth_2
            if( have_rows('gr_goth_3') ):

                  endwhile;
                endif;

            endif;
            //end gr_goth_4
            //end goth
          endwhile;
        endif;
        //end lnxd
      endwhile;
    endif;
    //end dtkpxd

I want this loop to store variable data in $array_save like this:

$array_save=array(
    '0'=> array(
        '0'=>$tlnxd,
        '1'=>array(

Variable $i to show more such array. Is there any solution to this? My algorithm is not very good. Actually this is an exercise that really hurts me, looking forward to your help. Thank you very much!
