从父文件运行PHP函数

Question

I need some help for a problem i'm facing. I've look on the web but i only found more usual issues which cannot solve mine.

The main idea is to run PHP functions like get_included_files(), get_defined_vars(), debug_backtrace() from the parent file.

In my code i have a PHP file, let's call it A.php which is including another PHP file, let's say B.php. I would like to run for exemple get_included_files() into B.php to get the files included in A.php.

Something similar to parent:: but for PHP files and not oriented object programming. I'm aware that it could be a security flaw, that's why i'm not sure it is possible, but i ask to be sure.

To be the clearest possible, here is an example :

A.php

include 'B.php';
include 'C.php';
include 'D.php';

get_includes();

B.php

function get_includes()
{
    $included_files = get_included_files();
    print_r($included_files);
}

And i need the $included_files var to contain array('B','C','D'). My problem is the PHP functions getting the included files from the file it's launched in, not from the parent (with this code, the $included_files is empty).

Consider the example:

a.php

function a(){
    echo "a";
}

function b(){
    echo "b";
}

b.php

include "a.php";

echo a();//echoes a

echo b();//echoes b
