Re: Session Documentation

Hi Curt!

I'm a involved on the php-general list helping people out. After repeated questions being asked on that list kind of force me to join this list to see what has/is been going on with the documentation. Plus I would be able to help with making the documentation clearer.

Welcome :)

One of the big problems on the list is sessions. The documentation as it exists now is rather confusing and misleading with the differences between php versions and session handling. So I'm rather inspired right now to re-write the session documentation to clarify how sessions behave.

Great.

In Handling different methods of session data there are currently three different ways: Currently something like

     session_start();
     $_SESSION['var'] = 'yada';

before:

    session_start();
    $HTTP_SESSION_VARS['var'] = 'yada';

and if register globals is on:

    session_start();
    session_register('var');
    $var = 'yada';

The last example, i usually discourage people using and wonder if that should even be documented on the 'session' page. I'm also not sure if that should be a deprecated functionality of php since register_globals was defaulted to off.

Every method should be documented clearly, there are codes using these, and people who need to use/maintain/update such code need to find documentation on it. Still as register_globals is off by default, that does not mean that users have it off. There is many ready made code still using register_globals, so some people are forced to set it to on.

There are other things that I would like to help with but as soon as i get a cvs account and more involved at how things work, I'll be sure to make everyone aware of them :)

Every help is appreciated. Goba
