Java HTTP Php Server

Question

I have a Java App that creates a local HTTP Webserver on Port 8080. Is there any possible Way how I can use/ install Php on it? I searched on google about this but couldnt find any help..... Any Help is appreciated!

My Code so far:

package minet;

import java.util.*;
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.*;
import java.net.*;

public class main {
    private static ServerSocket serverSocket;

    public static void main(String[] args) throws IOException {
        JFrame ip = new JFrame();
        JTextField field = new JTextField();
        field.setText("http://" + getIP() + ":8080");
        field.setEditable(false);
        field.setBounds(10, 10, 380, 110);
        ip.add(field);
        JButton shutdown = new JButton("Shutdown Minet");
        shutdown.setBounds(30, 120, 340, 50);
        ip.add(shutdown);
        ip.setLocationRelativeTo(null);
        ip.setSize(400, 200);
        ip.setLayout(null);
        ip.setVisible(true);
        shutdown.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                System.out.println("Shutting down Minet...");
                field.setText("Shutting down Minet...");
                setTimeout(() -> System.exit(0), 1000);
            }
        });

        serverSocket = new ServerSocket(8080); // Start, listen on port 8080
        while (true) {
            try {
                Socket s = serverSocket.accept(); // Wait for a client to connect
                new ClientHandler(s); // Handle the client in a separate thread
            } catch (Exception x) {
                System.out.println(x);
            }
        }
    }

    public static void setTimeout(Runnable runnable, int delay) {
        new Thread(() -> {
            try {
                Thread.sleep(delay);
                runnable.run();
            } catch (Exception e) {
                System.err.println(e);
            }
        }).start();
    }

    private static String getIP() {
        // This try will give the Public IP Address of the Host.
        try {
            URL url = new URL("http://automation.whatismyip.com/n09230945.asp");

             * String, we can check it's length and if length is not greater than zero, then
             * we can go for LAN IP or Local IP or PRIVATE IP

(Stackoverflow doesnt likes that many code... Thats why i have this external Link...)

Answer 1

From your question I understood that you used to use PHP as a web programing language. And you want to make an application in Java that shows some pages from PHP Web Server.

For this I think you need to include Built-in web server in your application. You just need to download it, uncompress it in your application path or wherever you want. You can find an INSTALL file in the directory. Install it as it shown, then start web server by:

$ cd path/to/built-in/php/web/server
$ php -S localhost:8000

Executing cmd commands is shown in this post. You may change port number as you want.

Another variant is you will need to include compressed Apache and PHP in your application installation package, then uncompress it, and edit config files programmatically, and after your application will be installed on some computer.

For showing pages from the PHP Web Server you just need to use WebView. An example of how to use it in Swing is shown here or you may use JavaFX directly without Swing if you want, because WebView is a part of JavaFX.
