get_included_files

(PHP 4, PHP 5)

get_included_filesReturns 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

Example #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";
}

?>

以上例程会输出:

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

注释

Note:

Files included using the auto_prepend_file configuration directive are not included in the returned array.

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.

If you want to get the relative path of an included file, from within itself use this function. If you ever have a include file thats path may not be static, this can save some time.

<?php
 
function get_current_files_path($file_name)
 {
  
//find the current files directory
  
$includes = get_included_files();
  
$path = "";
   for (
$i=0; $i < count($includes); $i++)
   {
    
$path = strstr($includes[$i], $file_name);
     if (
$path != false)
     {
      
$key = $i;
       break;
     }
   }
  
$path = str_replace(getcwd(), "", $includes[$key]);
  
$path = str_replace("\\", "/", $path);
  
$path = str_replace($file_name, "", $path);
  
$path = ltrim($path, "/");
  
   return
$path;
 }
?>

If you want to avoid the filepaths, just wrap get_included_files() inside preg_replace() to get rid of path info:

<?php
$filenames
= preg_replace("/\/.*\//", "", get_included_files());
?>

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.

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.

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.
