Memcache::connect — Open memcached server connection
$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.
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.
portPoint to the port where memcached is listening for connections. Set this parameter to 0 when using UNIX domain sockets.
Please note: port defaults to
memcache.default_port
if not specified. For this reason it is wise to specify the port
explicitly in this method call.
timeoutValue 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.
When the port is unspecified, this method defaults to the
value set of the PHP ini directive
memcache.default_port
If this value was changed elsewhere in your application it might lead to
unexpected results: for this reason it is wise to always specify the port
explicitly in this method call.
Restituisce TRUE in caso di successo, FALSE in caso di fallimento.
