# get_included_files

(PHP 4, PHP 5)

get_included_files — Returns an array with the names of included or required files

### Description

array get_included_files ( void )

Gets the names of all files that have been included using include, include_once, require or require_once.

### Return Values

Returns an array of the names of all files.

The script originally called is considered an "included file," so it will be listed together with the files referenced by include and family.

Files that are included or required multiple times only show up once in the returned array.

### Changelog

Version | Description
--- | ---
4.0.1 | In PHP 4.0.1 and previous versions this function assumed that the required files ended in the extension .php; other extensions would not be returned. The array returned by get_included_files() was an associative array and only listed files included by include and include_once.

### Examples

Example #1 get_included_files() example

`<?php
// This file is abc.php
include 'test1.php';
include_once 'test2.php';
require 'test3.php';
require_once 'test4.php';
$included_files = get_included_files();
foreach ($included_files as $filename) {
echo "$filename\n";
}
?>`

The above example will output:

    abc.php
    test1.php
    test2.php
    test3.php
    test4.php

### Notes

> Note:

> Files included using the auto_prepend_file configuration directive are not included in the returned array.
