As you are moving more and more into the Servlet world, you’ll probably will be using Servlet-Filters and normal Servlets todo some tasks.

If you then want to access Variables in a PHP Session, here’s how to do it:

The Quercus PHP-Session is not stored the same way as the normal Servlet HTTP-Session is stored. Quercus uses an own Session Manager that is capable of doing all this stuff that you know from PHP, like e.g. migrating Session-IDs (to prevent session-hijacking etc.).

To access this Session Manager, you first have to get a hand on the QuercusContext. In the current release (4.0.7) there is no easy way to get a hand on it if you are not inside a PHPModule or a PHP-Page. Thus I simply copied com.caucho.quercus.servlet.QuercusServlet to com.caucho.quercus.servlet.DCQuercusServlet and added this line to the end of the method:

  private void initImpl(ServletConfig config)
    throws ServletException
  {
....
      config.getServletContext().setAttribute("quercusContext", quercus);
 }

which exposes the QuercusContext as an Attribute in the ServletContext.

(Note: If you are running multiple QuercusServlets in your WebApp – which you probably shouldn’t – this might will be a problem)
(Note2: The package name com.caucho.quercus.servlet must be used, or else you will not have access to some package scoped properties used in the QuercusServlet)
Ok, so now we have access to the QuercusContext from every Servlet, Filter or JSF-Bean, horray

But how to use it?

Lets take a look at the following filter and its methods helping me to work with the PHP-Session:

public class LoginOutFilter implements Filter {

    QuercusContext context; // we store the reference to the quercusContext in the filter
    FilterConfig config; // the reference to the config 

...
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        config = filterConfig;
    }

    // looks up the QuercusContext the first time it is accessed
    // Beware: will return null if no PHP page has been rendered yet and the quercusContext is not already set.
    private QuercusContext getQuercusContext()
    {
        if(context == null)
        {
            context = (QuercusContext) config.getServletContext().getAttribute("quercusContext");
        }
        return context;

    }

    // find the PHP-Session Cookie in the array of Cookies provided by the browser
    public Cookie findPHPSessionCookie(Cookie[] cookies)
    {
        for(Cookie c : cookies)
        {
            if(c.getName().equals("PHPSESSID")){
                return c;
            }
        }
        return null;
    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
     if(someCondition)
     {
                // clear a PHP-Session, e.g. when logging out a user
                Cookie c = findPHPSessionCookie(((HttpServletRequest) servletRequest).getCookies());
                if(c != null){
                    QuercusSessionManager mng = getQuercusContext().getQuercusSessionManager();
                    String phpSessionId = c.getValue();
                    mng.removeSession(phpSessionId);
                }
     }

     if(someOtherCondition) {
                        QuercusSessionManager mng = getQuercusContext().getQuercusSessionManager();

                        SessionArrayValue val;
                        Cookie c = findPHPSessionCookie(((HttpServletRequest) servletRequest).getCookies());
                        String phpSessionId;
                        if(c != null)
                        {
        // we found a session cookie
                            phpSessionId = c.getValue();
                            val = mng.getSession(null, phpSessionId, new Date().getTime()  );
                            if(val == null)
                            {
        // but the session does not exist on the server, so create it
                                val = mng.createSession(null, phpSessionId, new Date().getTime());
                            }

                        }else
                        {
          // we haven't found a php-session cookie, so create a new session
                            val = mng.createSession(null,null,new Date().getTime());
                            phpSessionId = val.getId();
          // and store the appropriate cookie
                            Cookie newCookie = new Cookie("PHPSESSID", phpSessionId);
                            ((HttpServletResponse)servletResponse).addCookie(newCookie);
                        }
     // storing data in the session
                      String username = "myUsername";
                        val.put("ludata_suserid", username);
                        val.put("ludata_nusernr", someService.getUserId(username));
                        val.put("ludata_nstatusnr", someService.getUserStatus(username));
                        val.addUse(); // This is required for saving, else an IllegalStateException will be thrown
                        mng.saveSession(null, val);
       }
     }

The above code shows how to erase a session and how to add values to a session. To get values from a session, simply use val.get(..).

Attention: This currently only works if the page after the filter is not a Quercus Page itself (e.g. a Servlet or a JSF Page). I’m working on a solution for this

If you, like me, want to use managed beans from inside your php code, and find out, that jndi_lookup and java_bean() do not work (= return null every time), try this little method

function my_java_bean($name)
{
    $beanManager = quercus_get_servlet_context()->getAttribute("javax.enterprise.inject.spi.BeanManager");
    $beans = $beanManager->getBeans($name);
    if($beans == null || count($beans) < 1)
        return null;
    $object = $beanManager->getReference($beans[0], $beans[0]->getClass(),
            $beanManager->createCreationalContext($beans[0]));
    return $object;
}

1. Create your Datasource e.g. in Glassfish v3′s admin console… I named mine jdbc/postgresDS

2. copy the file pgsqljndi.php to /usr/share/php/DB/pgsqljndi.php (or wherever you include your PEAR stuff from..)

3. change the database connection creation part of your script to this:

$db = & DB::connect("pgsqljndi://java:comp/env/jdbc/postgresDS");
if(DB::isError($db))
{
// error handling
}

4. remove stuff like this from your scripts

$db->query("SET NAMES 'utf-8'; ");

Your database connection with PEAR::DB, Quercus, PostgreSQL, JDBC + JNDI should work now!

I just tried it out and it really rocks! Download, extract, start domain, running!
Even PHP Applications are easily possible: I will look further into this this weekend!

Unfortunately, also the mailing list did not respond to my mails, so I had to dig into the source alone.

The problem I had was, that although I added the profile-php-maven to my settings.xml, the archetypes where not recognized, resulting in an error-message like this, when trying to create a new project:

mvn archetype:generate -DarchetypeGroupId=org.phpmaven -

So.. maven does not recognize my profile, even not after upgrading to maven 2.2…. So I did checkout the source, and compiled the stuff myself:

svn checkout http://svn.key-tec.de/php-maven/trunk/ 

cd trunk/org.phpmaven.multimaster/

however, trying to build the project was not successfull because of miss-spelled directories and outdated dependencies

 mvn clean compile install

I fixed those with two small + simple commands:

svn mv maven-php-plugin org.phpmaven.plugin # rename directory
# replace outdated wagon-ftp dependency
for i in `find . -iname 'pom.xml' | grep -v svn`; do sed 's/1.0-20080208/1.0-beta-6/g' $i > ${i}_xx ; mv ${i}_xx $i; done

after this, a simple

mvn install

did the trick for me.

I'm now creating new php-maven projects like this:

I'm in contact with Christian Widemann from Key-Tec to resolve the outstanding problems.

I’ll use CAS (central authentication service) to enable a smooth transition from PHP to Java on the lyrics portal I’m working on.

Now, that I’ve got phpCAS working on a small sample application (the big trick was to compile PHP with curl support), I’ll switch the authentication mechanism of the current PHP-Application to phpCAS and will use the Java-pendant for the new Java applications.

Next, I’ll look into the integration of CAS with Spring-Security and on using CAS with Portlets, that will be interesting

Some links I’ve found quite useful:

1. CAS main homepage
2. phpCAS API Reference
3. phpCAS Wiki Page
4. Setup SSL on Tomcat 6
5. Using existing user-database
6. Using JDBC for Authentication
7. JavaDoc Class QueryDatabaseAuthenticationHandler
8. Spring Security Homepage
9. CAS with Portlets
10. Happy Sound: Lyrics to Farin Urlaub
