Memcache::pconnect

(PECL memcache >= 0.4.0)

Memcache::pconnectOpen memcached server persistent connection

Опис

mixed Memcache::pconnect ( string $host [, int $port [, int $timeout ]] )

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.

Параметри

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.

Значення, що повертаються

Returns a Memcache object або FALSE в разі помилки.

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
