Memcache::get — Retrieve item from the server

Açıklama

Memcache::get(string$key, int&$flags = ?): string

Memcache::get(array$keys, array&$flags = ?): array

Memcache::get() returns previously stored data of an item, if such key exists on the server at this moment.

You can pass array of keys to Memcache::get() to get array of values. The result array will contain only found key-value pairs.

Bağımsız Değişkenler

key: The key or array of keys to fetch.
flags: If present, flags fetched along with the values will be written to this parameter. These flags are the same as the ones given to for example Memcache::set(). The lowest byte of the int is reserved for pecl/memcache internal usage (e.g. to indicate compression and serialization status).

Dönen Değerler

Returns the value associated with the key or an array of found key-value pairs when key is an array. Returns false on failure, key is not found or key is an empty array.
