[protocode]

Thank you very much this has set me in the right direction.

I added some more and got basically what I was looking for.

PHP Code:

$aPC = array('top'=> 

                    (

                    array(

                            'A_1'=>

                                    array(

                                            'B_1'=>array('C_1' => 'Test C_1','C_2'),

                                            'B_2'=>array('C_3') 

                                            ),

                            'A_2'=>

                                    array(

                                            'B_3'=>array('C_4')

                                          )

                    )

            )

        );



foreach ($aPC as $k=>$v)

{

  //echo $k.'<br />';

  foreach ($v as $kk=>$vv)

  {

    echo $kk.'<br />';

    foreach($vv as $kkk=>$vvv)

    {

      echo "&nbsp;".$kkk.'<br />';

      foreach($vvv as $kkkk=>$vvvv)

      {

          echo "&nbsp;&nbsp;".$vvvv.'<br />';

      }    

      }

  }

}
