( resource result, int row [, mixed field] )
Retrieves the contents of one cell from a MySQL result set.
When working on large result sets, you should consider using one
of the functions that fetch an entire row (specified below). As
these functions return the contents of multiple cells in one
function call, they're MUCH quicker than
mysql_result(). Also, note that specifying a
numeric offset for the field argument is much quicker than
specifying a fieldname or tablename.fieldname argument.
