[Resolved] Question about sessions

[Tomz]

Hi,

I am storing a database value in a session. This value is a number.

something like this:

        $query = "select * from access";
        $result = mysql_query($query);

    if(!$result) {die("Query didn't work " . mysql_error());}
            else{
                while ($row = mysql_fetch_array($result) ){

                $_SESSION['catagory']  = $row["catagory"];}

Lets say the number it retrieves from the database is 32
It seems as if this number is stored into this session as text, like:

$_SESSION['catagory'] = "32";

instead of

$_SESSION['catagory'] = 32;

Is this possible? If so, what should I do to make sure it's stored as a number (like : $_SESSION['catagory'] = 32)?

I ask this because when I use this session variable later on in my script things get messed up, when I replace the session variable for a number, things work fine.

Would casting it work?

PHP is not a strongly typed language and generally treats all numbers as if the are strings, unless you tell it to do otherwise. This doesn't create problems in most contexts. If you run into a situation where it does, there are ways to force the issue. Read this page of the manual in particular:
