<para>
Returns an array, which corresponds to the next result row or &false; in
case of error or there are no more rows in the result.
</para>
<para>
<function>oci_fetch_array</function> returns an array with both
associative and numeric indices.
</para>
&database.fetch-null;
<para>
An optional second parameter can be any combination of the following
constants:
<simplelist>
<member>
<constant>OCI_BOTH</constant> - return an array with both associative
and numeric indices (the same as <constant>OCI_ASSOC</constant>
+ <constant>OCI_NUM</constant>). This is the default behavior.
</member>
<member>
<constant>OCI_ASSOC</constant> - return an associative array
(as <function>oci_fetch_assoc</function> works).
</member>
<member>
<constant>OCI_NUM</constant> - return a numeric array,
(as <function>oci_fetch_row</function> works).
</member>
<member>
<constant>OCI_RETURN_NULLS</constant> - create empty elements
for the &null; fields.
</member>
<member>
<constant>OCI_RETURN_LOBS</constant> - return the value of a LOB
of the descriptor.
</member>
</simplelist>
Default <parameter>mode</parameter> is <constant>OCI_BOTH</constant>.
</para>
<para>
It should be mentioned here, that <function>oci_fetch_array</function>
is <emphasis>insignificantly</emphasis> slower, than
<function>oci_fetch_row</function>, but much more handy.
</para>
<note>
<simpara>
Oracle returns all field names in uppercase and associative indices in the result array will be uppercased too.
