Memcache::setServerParams Changes server parameters and status at runtime &reftitle.description; boolMemcache::setServerParams stringhost intport inttimeout intretry_interval boolstatus callbackfailure_callback Memcache::setServerParams changes server parameters at runtime. You can also use the memcache_set_server_params function. This function has been added to Memcache version 2.1.0. &reftitle.parameters; host Point to the host where memcached is listening for connections. port Point to the port where memcached is listening for connections. This parameter is optional and its default value is 11211. timeout Value in seconds which will be used for connecting to the daemon. Think twice before changing the default value of 1 second - you can lose all the advantages of caching if your connection is too slow. retry_interval Controls how often a failed server will be retried, the default value is 15 seconds. Setting this parameter to -1 disables automatic retry. Neither this nor the persistent parameter has any effect when the extension is loaded dynamically via dl. status Controls if the server should be flagged as online. Setting this parameter to &false; and retry_interval to -1 allows a failed server to be kept in the pool so as not to affect the key distribution algoritm. Requests for this server will then failover or fail immediately depending on the memcache.allow_failover setting. Default to &true;, meaning the server should be considered online. failure_callback Allows the user to specify a callback function to run upon encountering an error. The callback is run before failover is attempted. The function takes two parameters, the hostname and port of the failed server. &reftitle.returnvalues; &return.success; &reftitle.examples; addServer('memcache_host', 11211, false, 1, 1, -1, false); // Bring the server back online $memcache->setServerParams('memcache_host', 11211, 1, 15, true, '_callback_memcache_failure'); /* procedural API */ $memcache_obj = memcache_connect('memcache_host', 11211); memcache_set_server_params($memcache_obj, 'memcache_host', 11211, 1, 15, true, '_callback_memcache_failure'); ?> ]]> &reftitle.seealso; Memcache::addServer Memcache::getServerStatus
