Memcache::connectOpen memcached server connection


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.



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.


Point to the port where memcached is listening for connections. Set this parameter to 0 when using UNIX domain sockets.


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.

Return Values

Returns TRUE on success or FALSE on failure.
