PHP package manager

does anyone know a package manager library for PHP (as e.g. apt or yum for linux distros) apart from PEAR? I'm working on a system which should include a package management system for module management. I managed to get a working solution using PEAR, but using the PEAR client for anything else than managing a PEAR installation is not really the optimal solution as it's not designed for that. I would have to modify/extend it (e.g. to implement actions on installation/upgrade or to move PEAR specific files like lockfiles away from the system root) and especially the CLI client code is quite messy and PHP4. So maybe someone has some suggestions

• for an alternative PEAR client library which is easy to use and extend (the server side has some nice implementations like Pirum and pearhub)
• for completely different package management systems written in PHP (ideally including dependency tracking and different channels)
• for some general ideas how to implement such a PM system (yes, I'm still tinkering with the idea of implem开发者_运维问答enting such a system from scratch)

I know that big systems like Magento and symfony use PEAR for their PM. Magento uses a hacked version of the original PEAR client (which I'd like to avoid), symfony's implementation seems quite integrated with the framework, but would be a good starting point to at least write the client from scratch. Anyway, if anybody has suggestions: please :)

There is Composer also.

Have you checked Maven for PHP? I've only used Maven in the context of Java applications, but it's certainly:

• Easy to extend – it's really easy to implement Maven plugins
• Manages dependencies – distinguishing compile, test and runtime dependencies (though the compile/runtime distintion doesn't make sense in PHP).
• Repositories are trivial to put up – Apache with mod_dav will give you a working writable repository, but you also have Nexus.
• Distinguishes snapshot from stable artifacts; allows several policies for when to check for new snapshot artifacts and from which repositories get each type.

And many – many – more things.

PEAR2/Pyrus was built for package management for arbitrary applications. I believe it was modeled after the apt/yum architectures.

Helgi - core PEAR member - covers some of it here - http://www.slideshare.net/helgith/pear2-pyrus-the-look-ahead but the documentation is pretty solid too: http://pear.php.net/manual/en/pyrus.extending.installation.php
