For those of you who don't know, "universal constructor" is the name I give to PHP constructors that always and only take a single parameter. The parameter is an array of key-value pairs, which is then merged with a set of default keys and values. Finally, the array is unmarshalled, usually into object properties.

He talks about the benefits of using a constructor like this in your applications and how he's implemented it as a standard part of the Solar framework. Oh, and the sighting in the wild? It was in this MongoDB session handler.

Be sure to check out the comments for some other great opinions on this "universal constructor" idea, both for and against.

This entry is an extension to the current manual page for user authentication and is intended for folks who have already been through the basics of SolarPHP. What I hope to accomplish here is to show you how to setup user authentication using MySQL, something the manual currently does not elaborate upon.

He includes all of the bits you'll need to get it up and working - the code for the authentication, the configuration file setup, and the MySQL stable structure.

Solar_Registry is a class for storing singleton objects which are used usually for things like SQL objects and the response and request objects. Now what's interesting, is that in the new version of Solar a new configuration key registry_set was added for the Solar arch-class. You can use it to tell Solar to automatically add objects to the registry when it starts up.

He compares the two methods - manual loading and the automatic version and includes a "real world" example of loading up an SMTP object.

We're happy to announce the release of Solar 1.0.0alpha2. After almost a year of changes and improvements, this one has been a long time in coming. You can see the download-and-installation instructions here.

Changes include updates to Solar_Auth, Solar_Cache, Solar_Sql, some schema changes, additions of some new classes like Solar_Factory, Solar_Service_Akismet and lots more. Check out this blog entry for the complete list (along with what was changed in detail).

Oh yeah, did we mention the project now has a blog? Paul Jones and crew have whipped up a blog application (written with Solar, of course) they've launched to help the community keep track of the latest from the framework. The source for the blog will be coming soon for those who are looking to see how it all works.
