arrays

I have an array within an array.

$a = array ( 0 => array ( 'value' => 'America', ), 1 => array ( 'value' => 'England', ), )

How do I check if 'America' exists in the array? The America array could be any key, and there could be any number of subarrays, so a generalized solution please.

Looking on the php manual I see in_array, but that only works for the top layer. so something like in_array("America", $a) would not work.

Thanks.
