Memcache::connect

(PECL memcache >= 0.2.0)

Memcache::connect — Open memcached server connection

Descrição

bool Memcache::connect ( string $host [, int $port [, int $timeout ]] )

Memcache::connect() establishes a connection to the memcached server. The connection, which was opened using Memcache::connect() will be automatically closed at the end of script execution. Also you can close it with Memcache::close(). Also you can use memcache_connect() function.

Parâmetros

host: Point to the host where memcached is listening for connections. This parameter may also specify other transports like unix:///path/to/memcached.sock to use UNIX domain sockets, in this case port must also be set to 0.
port: Point to the port where memcached is listening for connections. Set this parameter to 0 when using UNIX domain sockets.
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.

Valor Retornado

Retorna TRUE em caso de sucesso ou FALSE em falhas.

The behavior of Memcache::connect() is to always reinitialize the pool from scratch regardless of any previous calls to addServer().



E.g.



$mmc = new Memcache()

$mmc->addServer('node1', 11211);

$mmc->addServer('node2', 11211);

$mmc->addServer('node3', 11211);



$mmc->connect('node1', 11211);



The last connect() call clears out the pool and then add and connect node1:11211 making it the only server.



If you want a pool of memcache servers, do not use the connect() function.



If you only want a single memcache server then there is no need to use the addServer() function.
