    count() vs. mysql_num_rows()

    They give the same result, so which one is better/faster to use?

    Depends upon your needs/use.

    Note: If you already have a $result, use mysql_num_rows() on it otherwise use SQL count(). Don't SELECT data just for a count.

    SQL count or PHP count? I believe the latter calls mysql_num_rows internally when passed a MySQL result set.
