Memcache::increment — Increment item's value

Beschreibung

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

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.

Hinweis: Do not use Memcache::increment() with item, which was stored compressed, because consequent call to Memcache::get() will fail.

Also you can use memcache_increment() function.

Parameter-Liste

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

Rückgabewerte

Returns new item's value on successIm Fehlerfall wird FALSE zurückgegeben..
