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.
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.

timeoutValue 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.

Приклад #1 Memcache::pconnect() example
<?php
/* procedural API */
$memcache_obj = memcache_pconnect('memcache_host', 11211);
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->pconnect('memcache_host', 11211);
?>pconnect() put error message to stderr if connection failed. This behavior may cause unexpected output.
use '@' infrom of `pconnect()` to avoid it.
<?php
$cache = new Memcache();
$stat = @$cache->pconnect('localhost', 11211);
if (false === $stat) {
// connect failed
}
// connect success
