Hi again Michael: Digging documentation I found out that this behaviour (string and int keys) is native for mysql_fetch_arrow() (found into the help: 'In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys. ')
So the question is answered. Thank you for your help.
