Using PHP-Java-Bridge to achieve interoperability between PHP and Java

PHP-Java-Bridge is a tool for interoperability between PHP and Java. It allows Java classes and methods to be called in PHP code and data can be passed between PHP and Java. In this article, we describe how to use PHP-Java-Bridge to achieve this interoperability and provide corresponding sample code.

1. Download and install PHP-Java-Bridge

First, we need to download and install PHP-Java-Bridge. The latest version of PHP-Java-Bridge can be obtained from the official website (http://php-java-bridge.sourceforge.net/pjb/). Once downloaded, extract it to an accessible directory on your web server.

2. Configure PHP-Java-Bridge

In the installation directory, find Java.incthe file and copy it to the directory where your PHP code is located. Then, Java.incconfigure PHP-Java-Bridge by editing the file. In the file, you can set the Java installation path, class path and other information.

3. Create Java class

Before starting to use PHP-Java-Bridge, we need to create some Java classes for PHP to call. The following is a simple Java class example that provides a Calculatorclass that contains two methods: addand multiply.

public class Calculator {
