}

An array of hosts or IP addresses that provide the memcache service. All hosts must use the same port.

A port number for the memcache connection

A boolean that flags whether to use compression

See below for information on using this parameters. If defined, then the hosts and ports are not used.

Allows setting of options

/*
* Example Options
*/
$memcacheClass->memCacheOptions = array(Memcached::OPT_HASH=>Memcached::HASH_MURMUR);

The memcached library supports use of the serverKey option, using the cacheDataObject

$cls = new \stdClass;
 
$cls->ttl = 1800;
$cls->serverKey = 'tt-server';
 
$SQL = "SELECT * FROM departments";
 
$result = $db->cacheGetAll($SQL,false,$cls);
