[PHP] Math: Adding DB numbers to PHP script number

[Ben Houlton]

I'm trying to add a number from my database ($id) and add it to a number (1)
so that the link with http://xxxxx/index.php?id=#(+1) (no +1 this is just
example) has a the right id number not the one before it.
But I'm stuck on the problem where the http://xxxxx/index.php?id=0 not the
latest id number.
Any help is appeciated
Thanks.
