Memcache::get
(PECL memcache >= 0.2.0)
Memcache::get — Retrieve item from the server
Description
$key
[, int &$flags
] )$keys
[, array &$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'));
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$var = $memcache_obj->get(Array('some_key', 'second_key'));
