            [newvalue] => 0000-00-00 00:00:00
            [6] => checked_out_time
            [field] => checked_out_time
            [7] => 0
            [live] => 0
            [8] => 2010-05-11 17:46:35
            [changedone] => 2010-05-11 17:46:35
        )

)

Now here u can see that the index "field" has repeated values i.e. "checked_out" and "checked_out_time" other indexes have single occurrence, now what should I do to select/grab the first occurrence of the repetitive values only?
