Memcache::set

(PECL memcache >= 0.2.0)

Memcache::setStore data at the server

설명

bool Memcache::set ( string $key , mixed $var [, int $flag [, int $expire ]] )

Memcache::set() stores an item var with key on the memcached server. Parameter expire is expiration time in seconds. If it's 0, the item never expires (but memcached server doesn't guarantee this item to be stored all the time, it could be deleted from the cache to make place for other items). You can use MEMCACHE_COMPRESSED constant as flag value if you want to use on-the-fly compression (uses zlib).

Note: Remember that resource variables (i.e. file and connection descriptors) cannot be stored in the cache, because they cannot be adequately represented in serialized state.

Also you can use memcache_set() function.

인수

key

The key that will be associated with the item.

var

The variable to store. Strings and integers are stored as is, other types are stored serialized.

flag

Use MEMCACHE_COMPRESSED to store the item compressed (uses zlib).

expire

Expiration time of the item. If it's equal to zero, the item will never expire. You can also use Unix timestamp or a number of seconds starting from current time, but in the latter case the number of seconds may not exceed 2592000 (30 days).

Example #1 Memcache::set() example

<?php
/* procedural API */

/* connect to memcached server */
$memcache_obj memcache_connect('memcache_host'11211);

/*
set value of item with key 'var_key'
using 0 as flag value, compression is not used
expire time is 30 seconds
*/
memcache_set($memcache_obj'var_key''some variable'030);

echo 
memcache_get($memcache_obj'var_key');

?>

Example #2 Memcache::set() example

<?php
/* OO API */

$memcache_obj = new Memcache;

/* connect to memcached server */
$memcache_obj->connect('memcache_host'11211);

/*
set value of item with key 'var_key', using on-the-fly compression
expire time is 50 seconds
*/
$memcache_obj->set('var_key''some really big variable'MEMCACHE_COMPRESSED50);

echo 
$memcache_obj->get('var_key');

?>
