Memcache::connect — Open memcached server connection
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
.
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.
Example #1 Memcache::connect() example
<?php
$memcache_obj = memcache_connect('memcache_host', 11211);
$memcache = new Memcache;
$memcache->connect('memcache_host', 11211);
?>
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.
