Namespace function to make variables inside a namespace defenition.

[remco-pc]

Description

Well i have a framework which can handle multiple domains/subdomains inside a directory like /mnt/Domain/../Controller/Controller.php and inside that Controller there is a namespace like
namespace Domain/Www_example_com/Controller

Which can be handled by the autoloader.

But here it comes, my framework now has composer packages which can be installed inside a domain.

For example:
app install raxon/issue -frontend.host=... -backend.host=api...

<?php
namespace Domain\{{php.namespace.host(options('frontend.host'))}}\Application\Issue\Controller;

But the installation files then have no IDE support and this is currently done with my own scripting language.

Is there any reason why a namespace cannot contain a variable part like domain?

It's rarely needed. Allowing the namespace and/or class name to be dynamic would be problematic for opcache.

But the installation files then have no IDE support and this is currently done with my own scripting language.

Introducing this feature in the language doesn't automatically solve this problem though. IDE vendors will have to add support for these dynamic namespaces, but they also cannot magically guess what the namespace placeholder will be at runtime.

I'd reconsider whether you truly need dynamic namespaces in your application. If you think this is a good candidate for a future PHP addition, please start a discussion in the internals mailing list.
