DZone.com: Solarium PHP Solr client
New on DZone.com today there's an article from Bas De Nooijer talking about a new tool he's created to allow PHP to work directly with Solr (the popular searching platform from the Apache project) as a result of research he'd done from a previous article. The result is Solarium, an open sourced PHP client for Solr.
I've worked on a lot of Solr implementations in PHP applications. There are multiple solutions: manual HTTP requests, the solr-php-client library, custom implementations etcetera. However they all have one issue in common: they only handle the communication with Solr, many other important parts like query building are not covered at all. And the parts that are covered are usually over-simplified. [...] At first I developed it as a library for my own projects, but I've decided to turn it into an opensource project. The project is called 'Solarium' and can be found on github: https://github.com/basdenooijer/solarium
You can find complete details about the project over on its wiki including basics concepts of query flow and using the ping/select/update query methods to access your Solr server.
