Question

1. mysql_fetch_array()
2. mysql_fetch_assoc()
<

Answer 1

mysql_fetch_assoc() would probably be the better choice. There is a slight performance hit (the mysql extension needs to look up the column names, but that should only happen once, no matter how many rows you have), but probably not enough to justify using mysql_fetch_array() instead. mysql_fetch_array() can be useful if you're only selecting one column though.
