I faced similar situation where I need to call PHP function from java code and I have used below code to achieve this. In below code "/var/www/html/demo/demo.php" is the PHP file name and callToThisFunction() is the PHP function name. Hope this helpful for someone.

public static void execPHP() {

        Process process = null;

        try {

            process = Runtime.getRuntime().exec(new String[]{"php", "-r", "require '/var/www/html/demo/demo.php'; callToThisFunction();"});

            process.waitFor();

            String line;

            BufferedReader errorReader = new BufferedReader(new InputStreamReader(process.getErrorStream()));

            while ((line = errorReader.readLine()) != null) {
                System.out.println(line);
            }

            errorReader.close();

            BufferedReader outputReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

            while ((line = outputReader.readLine()) != null) {
                System.out.println(line);

            }

            outputReader.close();

        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        OutputStream outputStream = process.getOutputStream();
        PrintStream printStream = new PrintStream(outputStream);
        printStream.println();
        printStream.flush();
        printStream.close();

    }
