&warn.experimental.func;
<para>
<function>ingres_fetch_array</function> Returns an array that
corresponds to the fetched row, or &false; if there are no more
rows.
</para>
<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 other
column(s) of the same name, you must use the numeric index of the
column or make an alias for the column.
<informalexample>
<programlisting role="php">
<![CDATA[
<?php
ingres_query("select t1.f1 as foo t2.f1 as bar from t1, t2");
$result = ingres_fetch_array();
$foo = $result["foo"];
$bar = $result["bar"];
?>
]]>
</programlisting>
</informalexample>
</para>
<para>
<parameter>result_type</parameter> can be INGRES_NUM for
enumerated array, INGRES_ASSOC for associative array, or
INGRES_BOTH (default).
</para>
<para>
Speed-wise, 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>
