The obj_field() method returns the resultset record for the numeric column.

Returns: Mixed

<?php

try

    {
        printf ( "%s %s %s \n", $rs->obj_field( 0 ), 
                                $rs->obj_field( 1 ), 
                                $rs->obj_field( 2 );
    }
    
    echo $rs->obj_num_rows();

    if ( $dbh->obj_error() )
        throw new Exception( $dbh->obj_error_message() );
        
    while ( $obj = $rs->obj_fetch_object() ) 
    {
        printf ( "%s %s %s \n", $obj->color, 
                                $obj->size, 
                                $obj->price );
    }
    
    echo $rs->obj_num_rows();
    
    $rs->obj_free_result();
