Memcache::get
(PECL memcache >= 0.2.0)
Memcache::get — Retrieve item from the server
Description
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.
Parameters
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).
Return Values
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.
