PHP scripting engine plugin v0.1

Hi list,
I've been working on a PHP scripting engine plugin for Helma 1.x during the last two weeks. Although not finished. complete, or completely tested yet, I feel it is ready to be released to the public. A sample application is included. The plugin is based on the Quercus PHP scripting engine [1] by Caucho, which is part of the Resin [2] application server. Caucho offers both a GPLv2 and a commercial pro version. So far, the plugin makes use of the GPLv2 version only, which lacks Java bytecode compilation support. Caucho claims, that the commercial pro version (which offers Java bytecode compilation support is 4x faster than mod_php. I did some small standalone (i.e. without Helma) tests, which resulted in the pro version being at least twice as fast as mod_php and sometimes even faster as compiled Rhino JS. You can download the plugin from [3]. The release file is meant as overlay over a Helma 1.x (I only tested it with Helma 1.6.2) distribution. So to test it, simply extract a new Helma distribution [4] file and extract the plugin release file over it. The plugin release file contains three new libraries (quercus.jar, resin.jar and warp.jar), a test application (welcomePhp), an internal database for the test application (db/welcomePhp), static files for the test application and most important a simple script to start Helma (start_with_php.sh). IMPORTANT: For some reason (still need to find out why), the plugin only works when you start Helma like the included script file does it (i.e. it does not work, if you start Helma with the original start.sh script file which starts Helma via the launcher.jar). About Warp: Just to have it mentioned: the php plugin is hosted at Sourceforge. Warp, the project under which it is hosted, is a (my) fork of Helma 1.x. The intention of the fork is to rewrite and extend a pluggable Helma 1.x from the inside (compared to Helma NG). The fork allows me to do that in a flexible and permissive way. No need to look at the SVN yet, the current version does not differ from Helma (except being reformatted a little bit). Although it will soon differ substantially, it will always remain compatible to Helma 1.x (including future versions, at least that is the main goal). Additionally I will always provide functionality as Helma 1.x plugins (like the php plugin) too, if possible (if it is possible to have such functionality as Helma plugin). What was known as Warp before (the Warp repository implementation) [5] will soon be rewritten and included in Warp.

Hi Maks,
Quercus is pretty much the best product I was able to find to connect Java and PHP. Of course I do know, that native PHP is able to use Java, but with Quercus its even easier to use Java from within PHP, but most important the integration effectively works in both directions. After having finished the first release of the PHP plugin, I can judge the Quercus engine as being quite easy to integrate in any Java application. Especially extending the the PHP context with additional modules (like the GlobalObject does it for JS) is extremely easy and far more straightforward than what I could see how it is done for the JS context. The motivation however of writing the plugin was not that I prefer (Quercus) PHP over (Rhino) JS. Personally I like both languages and I can see advantages and disadvantages in both of them. Theoretically Helma was able to be extended with different scripting languages for years. But as far as I know, nobody ever did it. So the motivation was a proof of concept of the the scripting engine interface of Helma. My personal conclusion is, that the interface is at least good enough to allow various scripting language plugins to be developed. It could however be much better, if having a variety of different scripting languages would be a goal. Learning were things can be enhanced was another important motivation for writing the plugin. Btw, these are some of my personal favorites of using PHP as scripting language for Helma. class HopObject { public function size() { return "overriding can be so damn easy " . HopObjectJava::size(); } public function __get($name) { return "generic getters and setters, finally!"; } public function main_action() { import java.util.Date; echo new Date(); } } Kind regards, Daniel PS: Thanks for the pointer to script-10.jar! Only having resin-util.jar is not enough, but the script-10.jar might have the missing things. I will give it a try. Maksim Lin for technical support mailling lists wrote: Hi Daniel, Thanks for the pointer to Quercus! - I didnt even realise there was a Java implementation of PHP. I'm not sure if I would use it to write PHP scripts inside my Helma apps, but its very cool how you've been able to integrate running php scripts directly and pretty cleanly within Helma! However I could see myself using Quercus as a way of running PHP apps alongside Helma apps... Also I notice you include the Resin.jar but in thier .war download, it only seems to depend on resin-util.jar and script-10.jar which are much smaller (643+27kb vs 8.9Mb) so perhaps you might be able to use that instead for your package?
