Memcache::get

(PECL memcache >= 0.2.0)

Memcache::getRetrieve 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 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.

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 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.

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'));

$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host'11211);
