PHP: 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 . 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.
