Output current 'numerical' value of array

I have an array as such:

$items = array(
	'1'=> array('1'=>'Menu 1 Item 1', '2'=>'Menu 1 Item 2', '3'=>'Menu 1 Item 3'),
	'2'=> array('1'=>'Menu 2 Item 1', '2'=>'Menu 2 Item 2', '3'=>'Menu 2 Item 3')
);

Code (markup):

I have a FOR loop that processes this array and prints out the text for each element contained in the two sub-arrays. But now I also need to get the 'number' of the element that is currently being processed too - how can this be done?

 

Can't you just use the loop variables to determine this? i.e. - echo (i+1);

 

this may solve your problem.

foreach ($items as $key1=>$item)
{
   echo "Array #$key1 :<br/>";
   foreach($item as $key2=>$detail_item)
   {
      echo "  $key2. $detail_item<br/>";
   }
}
