There isn’t a whole lot of documentation about running PHP on Google App Engine to be found, but these links may be helpful (in a “note to self: I should try this when I find the time” kind of way):
- “Java/PHP integration” in the Quercus documentation
- “Google App Engine Java overview” for the GAE API in the Google documentation
- and “Using Google App Engine’s Datastore and Task Queues in PHP with Quercus” on the Caucho blog puts 2 and 2 together
If you stumble on these pages because you’re thinking about creating and deploying a PHP application on Google App Engine, you should take into account that although Quercus looks promising, there are bound to be bugs that you’ll sooner or later run into. There are, for example, issues with determining file length and there are problems with variable referencing in some rare/ complex cases. You have been warned! 😉
