PHP Manual: Retrieve item from the server

Description

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

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

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.

Examples

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'));
