Memcache::get
(PECL memcache:0.2-2.1.2)
Memcache::get — Retrieve item from the server
설명
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.
매개변수
- 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).
반환값
Returns the string associated with the key or FALSE on failure or if such key was not found.

You also can use array of keys as a parameter.
If such item wasn't found at the server, the result
array simply will not include such key.
