Memcache::get — Retrieve item from the server
$key
[, int &$flags
] ) : string$keys
[, array &$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.
keyThe key or array of keys to fetch.
flagsIf 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).
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.
Example #1 Memcache::get() example
<?php
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
$var = memcache_get($memcache_obj, 'some_key');
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$var = $memcache_obj->get('some_key');
/*
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.
*/
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
$var = memcache_get($memcache_obj, Array('some_key', 'another_key'));
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$var = $memcache_obj->get(Array('some_key', 'second_key'));
