PHP can run on the Java Virtual Machine (JVM) using implementations like P8 that compile PHP code to Java bytecode. This allows PHP applications to leverage Java libraries and Java applications to leverage PHP scripting. Integrating PHP and Java can provide benefits like allowing PHP developers to use cutting-edge Java runtimes and PHP apps to incorporate Apache POI, Eclipse BIRT, and Apache Lucene. Products like WebSphere sMash and Message Broker allow building apps using PHP, Java, and other JVM languages on a shared runtime.

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

11.
Some Code !
<?php
java_import( &quot;java.util.HashMap&quot; );
$map = new HashMap;
$map ->put( &quot;stuff&quot; , array ( 1 , 2 , 3 , 4 , 5 ));
var_dump( $map ->get( &quot;stuff&quot; ));
// prints: array(5) { ...

12.
Some more Code !
<?php
java_import( &quot;java.io.File&quot; );
class SubFile extends File {
function isThisCool() {
return TRUE ; // Way cool
}
}
$file = new SubFile( &quot;/&quot; );
var_dump( $file ->isDirectory());
var_dump( $file ->isThisCool());

13.
Last bit of Code !
<?php
java_import( &quot;java.util.ArrayList&quot; );
$list = new ArrayList();
$list ->add( &quot;Hello World!&quot; );
$list ->add( FALSE );
$list ->add( 1234567890 );
foreach ( $list as $key => $value ) {
echo &quot; $key $value &quot; ;
}

17.
Sorry, one more bit of Code !
class Dynamic {
def storage = [:]
def invokeMethod(String name, args) {
println &quot;Hello!&quot;
}
def getProperty(String name) {
storage[name]
}
def setProperty(String name, value) {
storage[name] = value
}
}
<?php
groovy_import( &quot;dynamic.groovy&quot; );
$foo = new Dynamic();
$foo ->bar();
$foo ->guff = &quot;Hello World!&quot; ;
echo $foo ->guff;
