  <para>
   Returns an array, indexed by both column name and position, representing a
   row in a result set. Note that the row returned by
   <function>db2_fetch_both</function> requires more memory than the
   single-indexed arrays returned by <function>db2_fetch_assoc</function> or
   <function>db2_fetch_array</function>.

       Requests a specific 1-indexed row from the result set. Passing this

   Returns an associative array with column values indexed by both the column
   name and 0-indexed column number. The array represents the next or
   requested row in the result set. Returns &false; if there are no rows left
   in the result set, or if the row requested by
   <parameter>row_number</parameter> does not exist in the result set.

     If you call <function>db2_fetch_both</function> without a specific row
     number, it automatically retrieves the next row in the result set. The
     following example accesses columns in the returned array by both column
     name and by numeric index.
