In PHP 4.0.1 and previous versions this function assumed that the
required files ended in the extension <literal>.php</literal>; other
extensions would not be returned. The array returned by
<function>get_included_files</function> was an associative array and
only listed files included by <function>include</function> and
<function>include_once</function>.
