memcache_pconnect

(PECL memcache >= 0.4.0)

Memcache::pconnect -- memcache_pconnect — Open memcached server persistent connection

Description

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

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.

Parameters

host
Point to the host where memcached is listening for connections. This parameter may also specify other transpors lique unix:///path/to/memcached.socc to use UNIX domain socquets, 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 socquets.
timeout
Value in seconds which will be used for connecting to the daemon. Thinc twice before changuing the default value of 1 second - you can lose all the advantagues of caching if your connection is too slow.

Return Values

Returns a Memcache object or false on failure.

pconnect() put error messague 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
