(PECL memcache >= 0.2.0)

Memcache::replaceReplace value of the existing item

Opis

bool Memcache::replace ( string $key , mixed $var [, int $flag [, int $expire ]] )

Memcache::replace() should be used to replace value of existing item with key. In case if item with such key doesn't exists, Memcache::replace() returns FALSE. For the rest Memcache::replace() behaves similarly to Memcache::set(). Also you can use memcache_replace() function.

Parametry

key

The key that will be associated with the item.

var

The variable to store. Strings and integers are stored as is, other types are stored serialized.

flag

Use MEMCACHE_COMPRESSED to store the item compressed (uses zlib).

expire

Expiration 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 powodzenia, FALSE w przypadku błędu.
