Memcache::addServer -- Add a memcached server to connection pool
Description
bool Memcache::addServer ( string host [, int port [, bool persistent [, int weight [, int timeout [, int retry_interval]]]]] )
Memcache::addServer() adds a server to the connection
pool. The actual connection is established on first use.
The connection, which was opened using
Memcache::addServer() will be automatically closed at the
end of script execution. Also you can close it with
Memcache::close().
You can also use the memcache_add_server() function.
Note:
This function has been added to Memcache version 2.0.0.
Parameters
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.
persistent
Controls the use of a persistent connection. Default to TRUE.
weight
Number of buckets to create for this server which in turn control its
probability of it being selected. The probability is relative to the
total weight of all servers.
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. Neither this nor the persistent
parameter has any effect when this extension is loaded dynamically
via dl().
Return Values
Returns TRUE on success or FALSE on failure.
