Memcache::connect — Open memcached server connection
Описание
$host
[, int $port
[, int $timeout

Список параметров
-
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
portmust 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.
Please note:
portdefaults to memcache.default_port if not specified. For this reason it is wise to specify the port explicitly in this method call. -
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.
Примечания
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.
