Working with an array of arrays

#include <Array.au3>
$string = "asdf qwer zxcv" & @CRLF & "1231 4564 7897" & @CRLF & "poui lkjh mnbv"
$array = StringRegExp($string, "(?U)(\w{4,4})\s(\w{4,4})\s(\w{4,4})\s?", 4)
; only way I know how:  temp arrays
For $i = 0 To UBound($array)-1
 $tempArray = $array[$i]
 For $j = 1 To UBound($tempArray)-1
  ConsoleWrite("[i,j]:[" & $i & "," & $j & "] [value]:[" & $tempArray[$j] & "]" & @CRLF)
 Next
Next

For $i = 0 To UBound($array)-1
 For $j = 0 To UBound($array[$i])-1
  ConsoleWrite($array[$i].[$j])
 Next
