note 91892 added to function.memcache-increment

Be careful to use Memcache::decrement() and never Memcache::increment() with a negative value. The check that prevents Memcache::decrement() from going negative is not in place with Memcache::increment(), so you can end up with a garbage integer on the order of 18 quintillion stored in place of the expected value. ---- Server IP: 208.69.120.35 Probable Submitter: 69.181.205.152 ---- Manual Page -- http://www.php.net/manual/en/function.memcache-increment.php Edit -- https://master.php.net/note/edit/91892 Del: integrated -- https://master.php.net/note/delete/91892/integrated Del: useless -- https://master.php.net/note/delete/91892/useless Del: bad code -- https://master.php.net/note/delete/91892/bad+code Del: spam -- https://master.php.net/note/delete/91892/spam Del: non-english -- https://master.php.net/note/delete/91892/non-english Del: in docs -- https://master.php.net/note/delete/91892/in+docs Del: other reasons-- https://master.php.net/note/delete/91892 Reject -- https://master.php.net/note/reject/91892 Search -- https://master.php.net/manage/user-notes.php
