Memcache::pconnect

(PECL memcache >= 0.4.0)

Memcache::pconnect — Open memcached server persistent connection

Descrizione

Memcache::pconnect(string $host, int $port = ?, int $timeout = ?): mixed

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.

Elenco dei parametri

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.
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.

Valori restituiti

Returns a Memcache object o false in caso di fallimento.

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
