Memcache::add
(no version information, might be only in CVS)
Memcache::add -- Add an item to the server
Description
bool
Memcache::add ( string key, mixed var [, int flag [, int expire]] )
Memcache::add() stores variable
var with key only if such
key doesn't exist at the server yet.
Memcache::add() returns FALSE if such key already
exist. For the rest Memcache::add() behaves
similarly to Memcache::set().
Also you can use memcache_add() function.
See example below.
