Problem with Session Variables

Hi there,

I´m new here, I still hope someone can help me.

I´ve got a little problem with PHP sessions. The thing is, I am initializing it right, it works just fine then, but after a little while, they seem to be disapearing...at least it looks like that. Heres an example:

function end_page(){
    login_box();
    if(isset($_SESSION['user_id'])){
        menu_intern();
    }

PHP:

This part works just fine, it recognizes the user_id and when I try to output it it works.
Right now I just try to output it in the menu_intern function, here:

function menu_intern(){
    echo('<span class="menu_right"><div class="newshead">Intern Area</div><br />');
    echo($_SESSSION['user_id']);
    echo('</span>');
}

PHP:

But it comes up empty. It happens with some other variable too at some point.
I also keep getting the:

error. From what I have found out, it should help to put the session_start() at the very beginning of the code (where it is now), which doesnt solve the error.

I have not worked very much with sessions (at least it was a while back..), so I think I am missing something.

If you´ve got any idea what might help with this I would appreciate it...thanks in advance !!

well. mostly this error means that there's an extra whitespace/blankspace at the beginning of <?php ... try to check, maybe the editor your using causes it.. i.e WSIWYG like MS Word.

 

nope...thats not it, double checked it.

Could it be a problem that it is in an extra header file which i include with "require_once" ?


*edit*Oh wow...that was stupid....noticed that in that function i wrote $_SESSSION ? Well I didnt...until now...
And you were right, the header error was because of the uft bom stuff...just had no editor showing it, thanks !*/edit*
