Memcache::set
(no version information, might be only in CVS)
Memcache::set -- Store data at the server
Description
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.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
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', 0, 30);
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_COMPRESSED, 50);
echo $memcache_obj->get('var_key');
?>
