     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.

     <function>oci_fetch_array</function> returns an array with both
     associative and numeric indices.

     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.
