PHP support
The PHP support in WebSphere sMash is provided by a PHP runtime implemented in Java. [2] . PHP scripts are
compiled into Java bytecode which then run on the Java Virtual Machine (JVM). This is similar in concept to the
approach taken by other projects such as JRuby and Jython, which run the Ruby and Python languages, respectively,
against the JVM. Running on the JVM allows direct, same process calls between PHP, Java and Groovy code
allowing applications to be assembled using a variety of languages.
In contrast to the approach taken by Quercus, the other JVM based PHP implementation, sMash is able to re-use
existing PHP extensions from PHP.net attaching them to the Java virtual machine via the Java Native Interface (JNI)
and an API layer called XAPI-C.
The runtime has a DBGp debug port allowing debug access from IDEs and debuggers which support the DBGp
protocol such as the Eclipse PDT project.
The PHP runtime does not have an identity outside of sMash so it is simply referred to as the "WebSphere sMash
runtime for PHP."
As of October 2008 WebSphere sMash is capable of running several well known PHP applications on a Java Virtual
Machine. These include SugarCRM [3] , phpBB [4] , WordPress [5] and Mediawiki [6] .
The PHP runtime supports close integration with the Java and Groovy languages through its Java/Groovy bridge.
This allows PHP scripts to use libraries written in Java and Groovy through a lightweight and extremely fast interop
layer. The Groovy bridge allows advanced features from Groovy to be accessed directly from PHP. Examples
include closures and Groovy metaobjects.
