A result set object is a logical representation of data rows returned by mysql_query() function on SELECT statements. Every result set object has an INTERNAL pointer USED to identify the current row in the result set. Once you GET a result set object, you can USE the following functions to retrieve detail information:
• mysql_free_result($rs) - Closes this result set object.
• mysql_num_rows($rs) - Returns the number rows in the result set.
• mysql_num_fields($rs) - Returns the number fields in the result set.
• mysql_fetch_row($rs) - Returns an array contains the current row INDEXED by field position numbers.
• mysql_fetch_assoc($rs) - Returns an array contains the current row indexed by field names.
• mysql_fetch_array($rs) - Returns an array contains the current row with double indexes: field position numbers and filed names.
• mysql_fetch_lengths($rs) - Returns an array contains lengths of all fields in the last row returned.
• mysql_field_name($rs, $i) - Returns the name of the field of the specified index.
