    Memcache::increment — Increment item's value

    Beschreibung

    Memcache::increment(string$key, int$value = 1): int|false

    Memcache::increment() increments value of an item by the specified value. If item specified by key was not numeric and cannot be converted to a number, it will change its value to value. Memcache::increment()does not create an item if it doesn't already exist.

    Hinweis:

    Do not use Memcache::increment() with items that have been stored compressed because subsequent calls to Memcache::get() will fail.

    Also you can use memcache_increment() function.
