get_included_files
(PHP 4, PHP 5, PHP 7)
get_included_files — Возвращает массив имен включенных в скрипт файлов
Описание
Получает имена всех файлов, которые были включены в скрипт функциями include, include_once, require или require_once.
Возвращаемые значения
Возвращает массив имен всех файлов.
Скрипт, который был загружен изначально, рассматривается как "включенный файл", поэтому он также попадет в список файлов включенных функцией include или другими.
Файлы добавляемые в скрипт неоднократно попадут в массив только в одном экземпляре.
Примеры
Пример #1 Пример использования get_included_files()
<?php
// Этот скрипт расположен в файле 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";
}
?>
Результат выполнения данного примера:
abc.php test1.php test2.php test3.php test4.php
Примечания
Замечание:
Файлы включенные в помощью директивы auto_prepend_file не попадут в возвращаемый массив.

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.
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.
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 $buf[0] != __FILE__;
}
blockit() and exit("You can not include a MAIN file as a part of your script.");
print "OK";
?>
So other script couldn't include main.php to modify its internal global vars.
This function aims to perform filtering of files that have been included :
<?php
function setIncludeFiles($arrayInc = array()){
$incFiles = get_included_files();
if((count($arrayInc)>0)&&(count($incFiles)>0)){
$aInt = array_intersect($arrayInc,$incFiles);
if(count($aInt)>0){
return false;
}elseif(count($aInt)<1) {
foreach($arrayInc as $inc){
if(is_file($inc))
include($inc);
else{
return false;
}
}
}
}else{
return false;
}
}
?>
Usage :
<?php
$toBeInclude = array('/data/your_include_files_1.php',
'/data/your_include_files_2.php',
'/data/your_include_files_3.php',
);
setIncludeFiles($toBeInclude);
?>
Return false if something goes wrong.
It's perhaps not clear from the existing docs that the returned list contains nested include files as well.
That is, if A.php includes B.php, and B.php includes C.php, the result returned when calling get_included_files() from inside A.php WILL contain 'C.php'.
This is a great way to emulate Python's '__name__ = "__main__"'
<?php
if(get_included_files()[0] === __FILE__) doStuff();
?>
