<para>
Returns an array of the names of all files that have been
included using <function>include</function>,
<function>include_once</function>, <function>require</function>
or <function>require_once</function>.
</para>
<para>
The script originally called is considered an "included file," so
it will be listed together with the files referenced by
<function>include</function> and family.
</para>
<para>
Files that are included or required multiple times only show up
once in the returned array.
</para>
<note>
<para>
Files included using the <literal>auto_prepend_file</literal>
configuration directive are not included in the returned array.
</para>

<para>
<example>
<title><function>get_included_files</function> example (<filename>abc.php</filename>)</title>
<programlisting role="php">
<![CDATA[
<?php
include 'test1.php';
include_once 'test2.php';
require 'test3.php';

$included_files = get_included_files();
foreach ($included_files as $filename) {
echo "$filename\n";

<para>
will generate the following output:
</para>
<screen>
<![CDATA[
abc.php
test1.php
test2.php
test3.php
test4.php
]]>
</screen>

</para>
<note>
<para>
In PHP 4.0.1pl2 and previous versions
<function>get_included_files</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>.
</para>

<para>

<function>include</function>,
<function>include_once</function>,
<function>require</function>,
<function>require_once</function>, and
