# Memcache::setServerParams

(no version information, might be only in CVS)

Memcache::setServerParams -- Changes server parameters and status at runtime

## Leírás

bool Memcache::setServerParams ( string host [, int port [, int timeout [, int retry_interval [, bool status [, callback failure_callback]]]]] )

Memcache::setServerParams() changes server parameters at runtime. You can also use the memcache_set_server_params() function.

> Megjegyzés: This function has been added to Memcache version 2.1.0.

## Paraméterek

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 loose 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 immediatly 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 attemped. The function takes two parameters, the hostname and port of the failed server.

## Visszatérési értékek

Siker esetén `TRUE` értékkel tér vissza, ellenkező esetben `FALSE` értéket ad.

## Példák

Példa 1. Memcache::setServerParams() example

`<?php
function _callback_memcache_failure($host, $port) {
print "memcache '$host:$port' failed";
}
/* OO API */
$memcache = new Memcache;
// Add the server in offline mode
$memcache->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');
?>`
