I gave a talk Wednesday at the Silicon Valley Google Technology Users’ Group on using Quercus in the App Engine. One of the examples I gave was using the low-level data API from PHP and scheduling PHP “tasks” using Task Queues. I’ll walk through the source of that demo here to give you an idea of how Quercus makes it easy to mesh a Java platform with PHP code. At the end, I’ll also give you an idea of what the next steps would be to take this demo and use the techniques in a real application or framework.

For version 4.0.1, we have added Quercus compilation support for other application servers including Tomcat, where before the interpreted mode was only available. The compiled mode is significantly faster than the interpreted mode (though the interpreted is still quite speedy compared to PHP on Apache). Quercus compilation will also work on Google App Engine, but there’s a requisite that files be pre-compiled.

Ever since Google App Engine (GAE) supported Java, it has opened a slew of other languages that GAE indirectly and unofficially supports. PHP is one of them through Quercus, our 100% Java clean-room implementation of the PHP language.

The nice folks organizing the Google I/O conference have given us an extra day to demo Quercus on the App Engine, so Nam and I’ll be there both Wednesday (12-6pm) and Thursday (12-4:45). It’s perfect timing too, because Nam has just finished an incredible demo that goes way beyond my meager efforts. He’ll be writing up a blog post about it soon, so I’ll have to just leave you in suspense until then…

By adding Java to their App Engine, Google has opened the door for a whole slew of languages that have been implemented on the JVM, now including PHP via Quercus. For the last couple of weeks, I’ve been looking at Google App Engine and what its possibilities are for Quercus. Some folks from a PHP shop in Britain got Quercus running, but the version they were using was pretty old and seemed to come from a bizarre cross slice of our SVN repository. We wanted to make sure that the current version of Quercus runs on GAE with all its performance and compatibility enhancements. So Scott created a GoogleQuercusServlet just for the task. I wrote up how to get started using Quercus on GAE and some notes about what PHP can and can’t do within GAE at the moment.
