Hi, being somewhat of a noob, I hope I'm using the right language to phrase
this question...
In a project I am working with, I have a multi-dimensional array in session
when a user logs in. Visually, it looks something like this...
OBJ_user
    username => value
    isAdmin => value
    modSettings =>  contacts => array
                    news => array
                    listings => firstname => value
                                lastname => value
                                active => value
                                phone => value
                    gallery => array
                    anothermod => array
    userID => value
    js => value
I'm trying to check the value of active for an if() statement and can't seem
to figure out the correct syntax to get it to work. I've tried
if($_SESSION["OBJ_user"]->modSettings["listings"]->active == "1") {
    then do something;
} else {
    then do something else;
}
if($_SESSION["OBJ_user"]["modSettings"]["listings"]["active"]) {
    then do something;
} else {
    then do something else;
}
if($_SESSION["OBJ_user"]["modSettings"]["listings"]["active"] == "1") {
    then do something;
} else {
    then do something else;
}
and none of them work even though I know the session value is there.

Any advice as to what I'm doing wrong?

Thanks,
verdon
The second of your three attempts should work fine, as should the third. 
Are you certain the actual value of active isn't 0? Try echoing the 
value of it to the screen, or do a print_r($_SESSION['OBJ_user']) to 
check the values and structure of the whole multidimensional array.
