Memcache::increment
(PECL memcache >= 0.2.0)
Memcache::increment — Increment item's value
Description
Memcache::increment
( string $key
[, int $value = 1
] ) : int|false
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.
Parameters
key- Key of the item to increment.
value- Increment the item by
value.
Return Values
Returns new items value on success or FALSE on failure.
