Memcache::increment — Increment item's value

설명

int Memcache::increment ( string $key [, int $value = 1 ] )

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.

Note:
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.

인수

key: Key of the item to increment.
value: Increment the item by value.

반환값

Returns new items value on success 실패 시 FALSE를 반환합니다.
