php: determine where function was called from

I have an autoloading function my_function($class) that could be called by any script. It is called by PHP’s spl_autoload_call() and that can happen everywhere. How do I script my_function($class) to detect when it is called by a specific $file?

Something like:

$file = '/htdocs/project/whatever.php';
if ($caller_file == $file) {
    ...

How do I find $caller_file?
I do understand this question is confusing but I can’t put it in better words right now. So if you have any problem understanding just let me know in the comments.

Edit (Context) I want to make the script load a different class’s file if the file the autoloader would load is the same in which the autoloader is called.

For example giving:

namespace Something;
class Random extends Random {}

should not load itself, but a different file in which we have:

namespace Something;
class Random { ... }

In other words:

What if I’m defining MyName\Class in a/class.php and I want to extends itself with MyName\Class extends \MyName\Class (inside a/class.php) but I want the autoloader to look \MyName\Class in b/class.php when it is asked within a/class.php?

Have you tried debug_backtrace() ?
