Tricks | scripting PHP and Java
Another idea of PHP is its ability to invoke methods of existing Java objects, which allows you to integrate PHP into existing java-based applications. If you are in your workplace to promote PHP, then you find a big blow to the beautiful point, you know, Java this stuff everywhere.
To use this functionality, you need to install the Java Virtual Machine (JVM) on the server. If you plan to install (or have already installed) JDK from Sun, Kaffe, IBM or Blackdown, you are now in the right path.
When you configure PHP, you will need to add--with-java parameters to the configuration instructions and then modify your php.ini file. The following lines are typically modified in php.ini:
[Java]
Java.library.path=/path/to/library
java.class.path=/classpath/
Extension_dir=/path/to/extensions
Extension=libphp_java.so
However, please note that these changes are dependent on your installation type. You should read the Readme file in the Ext/java directory under your PHP installation directory to learn more about the Java feature settings.
Here's a simple example: a PHP script that creates a new Java object. The script will then get some Java attributes and print them out. This is also a good example of COM.
?
$system = new Java ("Java.lang.System");
echo "<p>java Version =". $system->getproperty ("Java.version"). "<br>";
echo "Java vendor =". $system->getproperty ("Java.vendor"). "</p>";
?>
If you already have knowledge of Java, you must help the developer do the project well. These types of integration features are bound to be the key to future PHP development and acceptance, so the future of PHP will be much better with more people doing the work.
