Memcache::increment — Increment item's value
Описание
int Memcache::increment
( string $key
[, int $value
] )
Memcache::increment() increments value of the item on the specified value . If item with key key was not numeric and cannot be converted to number, it will change it's value to value . Memcache::increment() does not create an item if it didn't exist.
Also you can use memcache_increment() function.Замечание: Do not use Memcache::increment() with item, which was stored compressed, because consequent call to Memcache::get() will fail.
