<error>
Warning: Variable passed to each() is not an array or object in
D:\projects\kf10\test65.php on line 43
</error>
Line 43 in the error output refers to the "while" control structure. I can
not seem to define $level as the array $level_1 or $level_2, depending on
the $_SESSION['user']['level'] value (which can also be "1" or
"2"). Any
thoughts on how to do this? I tried using a switch statement like:
switch ($_SESSION['user']['level']) {
case "1":
$level = $level_1;
break;
case "2":
$level = $level_2;
}
But this didn't work either. Any help would be greatly appreciated.
