The difference between mysql_fetch_array and $db->fetch_array?

[Attilitus]

I actually was able to find a solution by using $db->fetch_row. The problem was that I was using numeric keys for certain result sets (which was something I would have prefered not to change because it was quite useful.)

Oddly enough $db->fetch_array does not appear to be fully inter-changable with mysql_fetch_array in this regard. But as I said $db->fetch_row worked perfectly in those specific cases.
