   Returns an array of the names of the declared classes in the current

  <note>
   <para>
    In PHP 4.0.1, three extra classes are returned at the beginning of
    the array: <classname>stdClass</classname> (defined in
    <filename>Zend/zend.c</filename>),
    <classname>OverloadedTestClass</classname> (defined in
    <filename>ext/standard/basic_functions.c</filename>)
    and <classname>Directory</classname>
    (defined in <filename>ext/standard/dir.c</filename>).
   </para>
   <para>
    Also note that depending on what libraries you have compiled
    into PHP, additional classes could be present. This means that
    you will not be able to define your own classes using these
    names. There is a list of predefined classes in the <link
    linkend="reserved.classes">Predefined Classes</link> section of
    the appendices.
