For debugging, I would suggest some crude but readable debugging, like this:
function trace($a) { print "".var_export($a, 1)."
"; }
// then you can do:
trace($array);
As for your question, you can access the methv key like this: $array[0][1173627548]['methv'] (or $array[1173627548]['methv'] if the above trace is the full $array variable).
