get_included_files

(PHP 4, PHP 5)

get_included_files — Liefert ein Array mit den Namen der includierten Dateien

Beschreibung

array get_included_files ( void )

Gibt die Namen aller Dateien zurück die mit include, include_once, require oder require_once eingebunden wurden.

Rückgabewerte

Gibt ein Array mit Dateinamen zurück.

Das ursprünglich aufgerufene Skript wird auch als includierte Datei angesehen und damit zusammen mit den Namen der tatäschlich mit include etc. eingebundenen Dateien zurückgegeben.

Dateien die mehrfach eingebunden werden erscheinen nur einfach im Ergebnisarray.

Changelog

Version Beschreibung
4.0.1 Bis einschließlich PHP 4.0.1 nahm diese Funktion an dass die includierten Dateien grundsätzlich auf .php enden und ignorierte Dateien mit anderen Endungen. Das zurückgegebene Array war assoziativ und enthielt nur mit include oder include_once eingebunden wurden.

Beispiele

Beispiel #1 get_included_files()Beispiel

<?php
// Diese Datei ist 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";
}

?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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

Anmerkungen

Hinweis:

Dateien die über die auto_prepend_file Konfigurationsdirektive eingebunden werden sind nicht Teil des Ergebnisarrays.

If you have a MAIN php script which you don't want to be included by other scripts, you could use this function. For example:

main.php:
<?php
function blockit()
{
  $buf = get_included_files();
  return $buf[0] != __FILE__;
}

blockit() and exit("You can not include a MAIN file as a part of your script.");

print "OK";
?>

So other script couldn't include main.php to modify its internal global vars.

Note that; you can't solve primary filename with get_included_files() to block directly accesses if you using a graphic file created with php or a stylesheet or a php script run under iframe and etc...

Actually, auto_prepend_files are listed with  get_included_files ( php 5.2 )

Something that's not noted in the docs, if a file is included remotely and you do a get_included_files() in the include itself it will *not* return the document that included it.

ie:
test2.php (server 192.168.1.14):
<?php

include("http://192.168.1.11/test/test3.php");

?>

test3.php (server 192.168.1.11):

<?php

$files = get_included_files();

print_r($files);
?>

returns:

Array ( [0] => /var/www/localhost/htdocs/test/test3.php )

Which means you can use get_included_files() to help intercept and prevent XSS-style attacks against your code.

The example is simply wrong as the behaviour of this function changed. It now in fact returns some absolut filenames (like you were using realpath() on them). In the past it returned the same string that was used to include/require the file.

example (file in /var/www ):
require('../www/somefile.php');
would be listed as ../www/somefile.php in the past but now as /var/www/somefile.php . The problem with the prior behaviour was that when you changed the working directory and used realpath() on the filenames than you got the wrong file or FALSE. I think the behviour was changed with PHP 5.0.0 (and therefor PHP 4.3.0) but I'm not sure. It is not mentioned here in the manual unfortunately.

If you wan`t to compare __FILE__ and $_SERVER['SCRIPT_NAME']
you could use realpath()
it strips out symlinks and things like that

realpath(__FILE__) == realpath($_SERVER['SCRIPT_NAME'])

In regards to
__FILE__ != $_SERVER['SCRIPT_FILENAME'] to check for a file as an include:

This only works if you are using PHP as an Apache module; when using PHP as a CGI binary on shared hosts, the filepaths may differ, even if they end up pointing to the exact same file.

For example, __FILE__ might be /home/SERVER/USER/SITE/test.php
and $_SERVER['SCRIPT_FILENAME'] might be /home/USER/SITE/test.php

Because of the SERVER included in the __FILE__ path, the comparison returns true, even though the file is not being included by any other file.

As is often the case, YMMV.  I tried the __FILE__ and SCRIPT_FILENAME comparison and found this:

SCRIPT_FILENAME: /var/www/cgi-bin/php441
__FILE__: /raid/home/natpresch/natpresch/RAY_included.php

As an alternative:

count(get_included_files());

Gives one when the script is standalone and always more than one when the script is included.

As of PHP5, this function seems to return an array with the first index being the script all subsequent scripts are included to.
If index.php includes b.php and c.php and calls get_included_files(), the returned array looks as follows:

index.php
a.php
b.php

while in PHP<5 the array would be:

a.php
b.php

If you want to know which is the script that is including current script you can use $_SERVER['SCRIPT_FILENAME'] or any other similar server global.

If you also want to ensure current script is being included and not run independently you should evaluate following expression:

__FILE__ != $_SERVER['SCRIPT_FILENAME']

If this expression returns TRUE, current script is being included or required.

Just FYI, the given example will return this ONLY if executed from the filesystem root:
abc.php
test1.php
test2.php
test3.php
test4.php

What makes this function useful is that it actually returns the complete path of each file.  Like this:
/path/including/document_root/to/abc.php
/path/including/document_root/to/test1.php
/path/including/document_root/to/test2.php
/path/including/document_root/to/test3.php
/path/including/document_root/to/test4.php
