How to use jena-SPARQL from web application?

I have no idea how I can make use of jena in my web search form (written in php (wamp)).
For example this code will display all the titles in my rdf data, but how can I run the process.php of my search-form to run the input text against it? The only thing I know so far is that I need to modify my jena code.java and link my php file to the jena code.class but that's not sufficient to write my code. I greatly appreciate if someone can guide me with any opinion, example, code... or whatever you think I'm missing. Thank you.

FileManager.get().addLocatorClassLoader(search.class.getClassLoader());
        Model model = FileManager.get().loadModel("newSample.rdf");
        String queryString = 
                "PREFIX rdf: http://www.w3.org/1999/02/22-rdf-syntax-ns#" +
                "PREFIX dc: http://purl.org/dc/elements/1.1/" +
                "SELECT ?title " +
                "WHERE { " +          

                "?x dc:title ?title ." +
                         "}";
        Query query = QueryFactory.create(queryString);
        QueryExecution qexec = QueryExecutionFactory.create(query, model);
        try {
            ResultSet results = qexec.execSelect();
            while ( results.hasNext() ) {
                QuerySolution soln = results.nextSolution();
                     Literal title = soln.getLiteral("title");
                           System.out.println(title);
                        }  }
