Define global function from within PHP namespace

Is it possible to define a global function from within a PHP namespace (within a file that has a namespace declaration)? If so, how?

<?php
namespace my_module;

# bunch of namespaced functions
# ...
# then I want to define a global function my_module()
# that is an alias to my_module\mymodule()

Functions defined in 'included' files have global scope.

So ( I haven't verified this ) you could put your function declaration in a small file, and include it.

Not quite what was envisaged in the question.

The other way to do it would be to create a local function, and in it use the 'global' keyword, and assign a closure to a global variable - which could then be used 'as a function' wherever you wanted it. I've certainly done this for ordinary variables, and I see no reason it should not work for closures.

It's possible but aside from being bad design, you will have to enclose your code within brackets for each namespace and won't be able to use namespace my_module; Instead it will have to be namespace my_module { ... }.

Example:

namespace my_module {

    function module_function()
    {
        // code
    }
}

namespace {
    // global namespace.

    function my_module()
    {
        // call your namespaced code
    }
}
