Memcache::get — Retrieve item from the server
Описание
$key
[, int &$flags
] )$keys
[, array &$flags
] )
Memcache::get() returns previously stored data if
an item with 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.
Список параметров
-
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).
Возвращаемые значения
Returns the string 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.
