Re: Random pick

Yes, $req_user_level is an int between 0 and 9. Yes, the other code worked great. Thank you for your response though. That is definitely a good way to cross check. Thanks again for your responses. Best, Karl On Jan 25, 2010, at 2:24 PM, Peter Beckman wrote:

Thank you for this as well. Question? What part is "in_array" playing? Is it comparing $req_user_level to array()? Because the text "Guest", etc.. is not in $req_user_level on the database. In other words, is it checking the value of $req_user_level to see if "Guest" is in it?

Sorry, I missed the question mark. in_array isn't appropriate here. The previous poster has it right, assuming $req_user_level is an integer of 0..9. $levels = array("Guest", "Regular User", 'Intl. User', ...)

 // the array is   0    ,      1        ,       2     , ...)

Going a little further:

    if (!empty($levels[$req_user_level])) {  // is both set and doesn't evaluate to false
        echo "The user is a {$levels[$req_user_level]}.\n";
    } else {
        //  The $req_user_level was not a valid level.
        echo "The returned req_user_level was not valid.\n";
    }

Which would output, if $req_user_level was 1 (one):

    The user is a Regular User.

Then you know you have a valid user level. Careful though -- sometimes 0 will be returned on a failure, depending on your SQL. Beckman ---------------------------------------------------------------------------
