PHP ODBC - What Is a Result Set Object Returned by odbc_exec()?

A result set object is a logical representation of data rows returned by odbc_exec() function on SELECT statements. Every result set object has an internal pointer used to identify the current row in the result set.

odbc_free_result($res) - Closes this result set object.
odbc_num_rows($res) - Returns the number rows in the result set.
odbc_num_fields($res) - Returns the number fields in the result set.
odbc_fetch_row($res) - Moving the internal pointer to the next row.
odbc_fetch_array($res) - Returns an array contains the next row indexed by filed names. The internal pointer is moved to the next row too.
odbc_fetch_object($res) - Returns an object representing the next row. The internal pointer is moved to the next row too.
odbc_field_len($res, $1) - Returns an array contains lengths of all fields in the last row returned.
odbc_field_name($res, $i) - Returns the name of the field of the specified index.
odbc_result($i) - Returns the value of the field specified by its position from the current row.
