  <para>
   This function is an extended version of
   <function>ingres_fetch_row</function>.  In addition to storing
   the data in the numeric indices of the result array, it also
   stores the data in associative indices, using the field names as
   keys.
  </para>
  <para>
   If two or more columns of the result have the same field names,
   the last column will take precedence. To access the another
   column or columns of the same name, you must use the numeric index of the
   column or make an alias for the column. For example:
   <informalexample>
    <programlisting role="php">
<![CDATA[
<?php

$result = ingres_query($link, "select ap_place as city, ap_ccode as country from airport where ap_iatacode = 'VLL'"); 
$result = ingres_fetch_array($result);
$foo = $result["city"];
$bar = $result["country"];

?>
]]>
    </programlisting>
   </informalexample>
  </para>
  <para>
   With regard to speed, the function is identical to
   <function>ingres_fetch_object</function>, and almost as quick as
   <function>ingres_fetch_row</function> (the difference is
   insignificant).
  </para>
  <para>
   By default, arrays created by <function>ingres_fetch_array</function> start
   from position 1 and not 0 as with other DBMS extensions. The starting position
   can be adjusted to 0 using the configuration parameter <link
   linkend="ini.ingres.array-index-start">ingres.array_index_start</link>.
  </para>
