    <para>
     The <function>mysqli_insert_id</function> function returns the ID generated 
     by a query on a table with a column having the AUTO_INCREMENT attribute. If
     the last query wasn't an INSERT or UPDATE statement or if the modified table
     does not have a column with the AUTO_INCREMENT attribute, this function will
     return zero.
    </para>
    <note>
     <para>
      Performing an INSERT or UPDATE statement using the LAST_INSERT_ID()
      function will also modify the value returned by the
      <function>mysqli_insert_id</function> function.
     </para>

   <refsect1>
    &reftitle.returnvalues;
    <para>
      The value of the <literal>AUTO_INCREMENT</literal> field that was updated 
      by the previous query. Returns zero if there was no previous query on the 
      connection or if the query did not update an <literal>AUTO_INCREMENT</literal>
      value. 
  </para>
  <note> 
   <para>
    If the number is greater than maximal int value, <function>mysqli_insert_id</function> 
    will return a string.
   </para>
