Memcache::replace -- memcache_replace — Replace value of the existing item

Açıklama

Memcache::replace(
    string $key,
    mixed $var,
    int $flag = ?,
    int $expire = ?
): bool
memcache_replace(
    Memcache $memcache,
    string $key,
    mixed $var,
    int $flag = ?,
    int $expire = ?
): bool

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().

Bağımsız Değişkenler

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).
