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.
Also you can use memcache_increment() function.Hinweis:
Do not use Memcache::increment() with items that have been stored compressed because subsequent calls to Memcache::get() will fail.
