Memcache::increment

Increment item's value ()
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. Memcache::increment() does not create an item if it didn't exist.

Note:

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.

Parameters

key: Key of the item to increment.
value: Increment the item by value. Optional and defaults to 1.

Return Values

Returns new item's value on success or FALSE on failure.
