Memcache::decrement -- Decrement item's value
Описание
int
Memcache::decrement ( string key [, int value] )
Memcache::decrement() decrements value of the
item by value. Similarly to
Memcache::increment(), current value of the item is
being converted to numerical and after that value
is substracted.
Parameter value is optional. It's default is 1.
Замечание:
New item's value will not be less than zero.
Замечание:
Do not use Memcache::decrement() with item, which was
stored compressed, because consequent call to
Memcache::get() will fail.
Also you can use memcache_decrement() /functions/?f=
See example below.
Memcache::decrement() does not
create an item if it didn't exist.
Memcache::decrement() returns item's new value on
success or FALSE on failure.
