Memcache::add
Opis
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.
Also you can use memcache_add() function.
Parametry
keyThe key that will be associated with the item.
varThe variable to store. Strings and integers are stored as is, other types are stored serialized.
flagUse MEMCACHE_COMPRESSED to store the item compressed (uses zlib).
expireExpiration time of the item. If it's equal to zero, the item will never expire. You can also use Unix timestamp or a number of seconds starting from current time, but in the latter case the number of seconds may not exceed 2592000 (30 days).
Zwracane wartości
Zwraca TRUE w przypadku sukcesu, FALSE w przypadku porażki. Returns FALSE if such key already exist. For the rest Memcache::add() behaves similarly to Memcache::set().
