Memcache::increment

(no version information, might be only in CVS)Memcache::increment -- Increment item's value

Description

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.
- Parameter value is optional. It's default value is 1.

Замечание: 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. See example below.
