PHP_EOL; // prints: Sun Oct 11 00:00:00 BST 1981 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) { ... Access Java methods and fields from PHP <?php java_import( "java.lang.System" ); echo System::currentTimeMillis(); try { System::getProperty( FALSE ); } catch (JavaException $exception ) { echo $exception ->getMessage(); } Static methods and fields are accessible too Types are automatically converted at boundary of PHP runtime Java exceptions can be caught and handled in PHP

Java Bridge – Extending Java in PHP <?php java_import( "java.io.File" ); class SubFile extends File { function SuperFile( $path ) { parent ::__construct( $path ); } function isThisCool() { return TRUE ; // Way cool } } $file = new Sub File( "/" ); var_dump( $file ->isDirectory()); var_dump( $file ->isThisCool()); PHP classes can extend Java classes
- 21. PHP- Java Bridge – Iterators and Overloads Signatures provide explicit control for overloaded methods <?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 " ; } Java iteration is bridged into PHP <?php java_import( "java.lang.String" ); $signature = new JavaSignature(JAVA_INT); var_dump(String::valueOf( $signature , 1234567890 ));
- 22. Java Bridge – More features… <?php java_import( "java.math.BigDecimal" , NULL, FALSE , "My_BigDecimal" ); $value = new My_BigDecimal( "1.18E+10" ); echo $value ; Import a Java class under a different name to avoid clashes <?php java_import( "java.lang.Comparable" ); echo (ReflectionClass::export( "Comparable" )); PHP reflection works on Java classes <?php java_import( "java.io.File" ); $file = new File( "/home/robinf" ); var_dump( $file ->Parent); //equivalent to: var_dump( $file ->getParent()); Java bean support provides field access for get/set method calls
