# get_included_files

(PHP 4 >= 4.0.0)

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

## Description

``array get_included_files` (void)`

Returns an array of the names of all files that have been included using include(), include_once(), require() or require_once().

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

Example 1. get_included_files() Example
    <?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";
    }

    ?>

will generate the following output:

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

> Note: In PHP 4.0.1pl2 and previous versions get_included_files() 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().

See also: include(), include_once(), require(), require_once() and get_required_files().
