get_included_files

(PHP 4, PHP 5, PHP 7, PHP 8)

get_included_files — 返回被 include 和 require 文件名的 array

说明

get_included_files(): array

返回所有被 include、 include_once、 require 和 require_once 的文件名。

返回值

返回所有文件名称的 array。

脚本最初被称为”被包含的文件“，所以脚本自身也会和 include 系列函数引用的脚本列在一起。

被多次 include 和 require 的文件在返回的 array 里只会列出一次。

范例

示例 #1 get_included_files() 范例


<?php
// 本文件是 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";
}

?>

以上例程会输出：

/path/to/abc.php
/path/to/test1.php
/path/to/test2.php
/path/to/test3.php
/path/to/test4.php

注释

注意:
使用 auto_prepend_file 配置指令所包含的文件不会包含在返回的数组里。

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.

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.

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'.

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.

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.

This is a great way to emulate Python's '__name__ = "__main__"'

<?php
  if(get_included_files()[0] === __FILE__) doStuff();
?>

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.
