# get_included_files

(PHP 4, PHP 5)

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

## 说明

array get_included_files ( void )

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

## 返回值

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.

## 更新日志

版本 | 说明
--- | ---
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().

## 范例

例 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"; } ?>`

上例将输出：

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

## 注释

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