I made the first public release of STPhp on the 9th of October. STPhp is a PHP-based string translation suite designed as a simple internationalization tool to work without requiring non-standard dependencies; only the core of php3 is required, which means STPhp can be easily used in places where you, the code creator or installer, do not have control over the php binaries or configuration. STPhp is designed with a simple architecture, allowing you to store your translations in the manner you choose, so as to provide the highest possible performance with the lowest possible maintenance overhead. STPhp functions by externalizing the messages from your application, storing them until your application requests them.
The manual for STPhp may be found here.
Other projects
For the last couple of weeks, I've been working more hours than not on a number of smaller projects. Now that STPhp has been released, two more should be released in the next two weeks. There should also be announcement/release of some of the documentation work I've completed; that should happen in the next couple of weeks as well.
