Memcache::connect

Description

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

Memcache::connect() establishes a connection to the memcached server. Parameters host and port point to the host and port, where memcached is listening for connections. Parameter port is optional, it's default value is 11211. Also you can define a timeout (in seconds), which will be used when connecting to the daemon. Think twice before changing the default value - you can loose all the advantages of caching if your connection is too slow.

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. See example below.

如果成功则返回 TRUE，失败则返回 FALSE。
