Just a thought: you might want to try doing array_search() against
$outerArray[0] - as that will search the outer array's first array -
which I believe is your unique IDs.
If your second array is values associated with your first array, you
might want to try keying your array by the unique id's you're
generating, and set the value to the 'aa' or 'bb' or whatever.
