Without knowing what the PHP application does makes it difficult to answer.

But you might possibly be better off reverse-engineering a clear set of features / user stories, and then the question would be, can I implement these features using Drupal.

Drupal can serve as a CMS Application Framework, but since it is extensible, and uses the module architecture to add more functionality to core, you will have to write a module, which either uses Drupal functionality or else hooks up Drupal to your via some form of integration. Both will require modules, which simply means code running in the Drupal namespace.

Hello,

Can you use Drupal core as a PHP development framework? Suppose you want
to create a custom in-house web application which is not necessarily
going to be a Drupal module. What would you use?


I am the maintainer of a custom PHP application. It's quite poorly
written and I'm stuck maintaining it. I have been thinking that I'd like
to rewrite it from scratch. I don't *need* any third party software to
rewrite it, but it occurred to me that the final product might be better
if I used a good PHP development framework. So I started googling for
PHP application frameworks and I hit a Wikipedia page saying that some
people use Drupal as a development framework. So I thought I'd ask about
that here. Any thoughts?


I don't have a solid idea of what I'm looking for. I'm just looking to
see what's available.

Cheers,
Daniel.
