[[wp>Memcached]] provides a controlled, server-based memory caching service. The server is reasonably easily configured and installed, but provides a sophisticated caching configuration. PHP support for the library is available through the PHP PEAR //memcache// or //memcached// libraries. If both are available, the //memcache// library will be used.

Your platform and PHP version will be the primary decision factors between using //memcache// or //memcached//. In general, the following guidelines can be used.

^ Platform  ^ PHP Version  ^ Library   ^
| Windows   | 5.x, 7.x     | [[https://pecl.php.net/package/memcache|PEAR Memcache library]] |
| Unix      | 5.x          | ::: |
| :::       | 7.x          | [[https://pecl.php.net/package/memcached|PEAR Memcached library]]|

It's also worth noting that compression is not supported with //memcached//. If you need cache compression, the //memcache// library is recommended.

For larger environments, distributed Memcache hosts can be specified.

===== Usage =====
<code php>

$db = NewADOConnection($driver='mysqli');

/*
 * Enable memcache
 */
$db->memCache = true;

/*
 * Add one or more servers, for use in distributed systems
 */
$db->memCacheHost = array('192.168.0.78', '192.168.0.79', '192.168.0.80'); 

/*
 * Optionally add the server port if it differs from the default
 */
$db->memCachePort = 11211;

/*
 * Use 'true' to store the item compressed (uses zlib)
 * Note; Compression is only supported using the memcache library. This
 *       parameter will be ignored when using the memcached library
 */
$db->memCacheCompress = false;

/*
 * We connect to the database, not the memcache server
 */
$db->connect('localhost','mysql-user','mysql-password','employees');
