Memcache::connect

(PECL memcache:0.2-2.1.2)

Memcache::connect — Open memcached server connection

说明

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.

参数

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.

返回值

如果成功则返回 TRUE,失败则返回 FALSE
