Memcache::pconnect — Open memcached server persistent connection
Memcache::pconnect() is similar to Memcache::connect() with the difference, that the connection it establishes is persistent. This connection is not closed after the end of script execution and by Memcache::close() function. Also you can use memcache_pconnect() function.
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.
Point to the port where memcached is listening for connections. Set this parameter to 0 when using UNIX domain sockets.
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.
