MEMCACHE.CONNECT(3) 1 MEMCACHE.CONNECT(3)
Memcache::connect - Open memcached server connection
SYNOPSIS
bool Memcache::connect (string $host, [int $port], [int $timeout])
DESCRIPTION
Memcache.connect(3) establishes a connection to the memcached server. The connection, which was opened using Memcache.connect(3) will be
automatically closed at the end of script execution. Also you can close it with Memcache.close(3). Also you can use memcache_connect(3)
function.
PARAMETERS
o $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.
o $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.
o $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.
NOTES
Warning
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.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES

$memcache_obj = memcache_connect('memcache_host', 11211);
