Why run PHP on the JVM ?

PHP is an awesome language for web dev
The Java Virtual Machine is a cutting edge language runtime
PHP + JVM = ♥

How PHP runs on the JVM <?php echo 'hello' ; System. out .println( "hello" );

How PHP runs on the JVM

P8: a PHP 5.2 runtime implemented in Java
Runs on any Java 5+ JDK

Extensibility

XAPI-C for existing C extensions
XAPI-J for new Java extensions
(extension language choice is opaque to scripts)
Debug via DBGp using Eclipse PDT
P8 Runtime SAPI-J Parser Interpreter P8 Engine Java Extensions C Extensions Stack Resources Classes Objects Variables AST XAPI-J XAPI-C Native code Compiler .class opcodes Cache Persistent class cache Debug API (DBGp) Runtime

Some Code ! <?php java_import( "java.util.HashMap" ); $map = new HashMap; $map ->put( "stuff" , array ( 1 , 2 , 3 , 4 , 5 )); var_dump( $map ->get( "stuff" )); // prints: array(5) { ...

Some more Code ! <?php java_import( "java.io.File" ); class SubFile extends File { function isThisCool() { return TRUE ; // Way cool } } $file = new SubFile( "/" ); var_dump( $file ->isDirectory()); var_dump( $file ->isThisCool());

Last bit of Code ! <?php java_import( "java.util.ArrayList" ); $list = new ArrayList(); $list ->add( "Hello World!" ); $list ->add( FALSE ); $list ->add( 1234567890 ); foreach ( $list as $key => $value ) { echo " $key $value " ; }

PHP apps + Java libraries
For example...

SugarCRM + Apache POI
Drupal + Eclipse BIRT
PhpBB + Apache Lucene
Your PHP app + ??? = profit

Java apps + PHP scripting
For example...

PHP in WebSphere sMash
Build Web apps quickly and easily in Java , Groovy and PHP .

“ The application is the server”
Lightweight runtime, not a Java EE environment
Browser-based development tooling
JVM Web Server Application Code Language Runtimes

Sorry, one more bit of Code ! class Dynamic { def storage = [:] def invokeMethod(String name, args) { println "Hello!" } def getProperty(String name) { storage[name] } def setProperty(String name, value) { storage[name] = value } } <?php groovy_import( "dynamic.groovy" ); $foo = new Dynamic(); $foo ->bar(); $foo ->guff = "Hello World!" ; echo $foo ->guff;

PHP in Message Broker

Message Broker “ connects anything to anything ”
Routes and transforms data along the way
Use graphical mapping, XSLT, ESQL, Java and now PHP !
With PHP, use a SimpleXML-inspired syntax to easily manipulate XML message formats.

PHP in CICS
Build RESTful services based on CICS assets using PHP
Transaction Server CICS assets: RESTful API to CICS assets SupportPac CA1S ... DB2 COBOL Java
