(PECL memcache >= 0.2.0)
Memcache::connect — Open memcached server connection
Beschreibung
$host
, int $port
= ?, int $timeout
= ?): boolMemcache::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.
Parameter-Liste
-
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 caseport
must also be set to0
. -
port
-
Point 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. -
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.
Rückgabewerte

Beispiele
Beispiel #1 Memcache::connect() example
<?php
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
/* OO API */
$memcache = new Memcache;
$memcache->connect('memcache_host', 11211);
?>
Anmerkungen
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.
