如何从java swing程序中打开php文件？

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class OpenPHPFile {
    public static void main(String[] args) {
        try {
            // 创建进程并设置要执行的命令
            ProcessBuilder processBuilder = new ProcessBuilder("php", "path/to/php/file.php");
            
            // 启动进程
            Process process = processBuilder.start();
            
            // 等待进程执行完成
            int exitCode = process.waitFor();
            
            if (exitCode == 0) {
                // 获取进程的输出流
                InputStream inputStream = process.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
                
                // 读取输出流内容
                StringBuilder output = new StringBuilder();
                String line;
                while ((line = reader.readLine()) != null) {
                    output.append(line);
                }
                
                // 将输出结果显示在网页显示组件中
                String result = output.toString();
                // TODO: 将result设置为网页显示组件的内容
            } else {
                // 进程执行失败
                System.out.println("Failed to execute PHP file.");
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
