PHP dynamically generate namespace based on folder structure

I have a folder structure like so:

index.php
app/
    controllers/
                folder1/
                        class.php

There is no namespace definition in class.php. Would it be possible to put class.php in a namespace generated from folder structure relative to index? So it would be loaded like:

new \app\controllers\folder1\classInFile();

Or is there no way to dynamically create namespaces?

The namespace needs to be defined inside of class.php if you can create the PHP source file dynamically, you can create the namespace dynamically.

A file containing a namespace must declare the namespace at the top of the file before any other code.

http://php.net/manual/en/language.namespaces.definition.php

I.e., you cannot execute any code before the namespace declaration, and afterwards it's too late. Notwithstanding introspective runtime hacks: no, it's not possible. Even if it was, it would depend on runtime information, like what folder the code is executed/included from. The namespace could be var\www\myproject\foo\bar\baz or just foo\bar\baz. How are you going to determine that? That's getting messy.

Really, just make it explicit, even if that means typing a little more. The namespace is part of the class's name. You should not generate names dynamically at runtime.

You shouldn't be dynamically generating namespaces, the namespace cannot be set and read at compile time.

In any case, the namespace is provided/defined before any code is executed.
