RE: [PHP-DB] Session variables and arrays

After a little more research I found out strlen will return 5 for a real array too, so throw that out. However, since gettype prints a string not an array, I just don't know. print_r prints the array, but you can iterate through it. Do you do this before your loop? reset($_SESSION['categories']); print_r($var) will set the pointer to the end of the array, so you have to reset it to the beginning before you iterate through it again. Maybe this is the problem?
