Memcached Object Cache provides a persistent backend for the WordPress object cache. A memcached server and the PECL memcache extension are required.

Memcached Object Cache

Hi!

It works out-of-box, just added the file and done! Awesome work here!

Only had to replace the constructor name at 424 to -> function __construct() - so we avoid a Warning at PHP7, for example.

Kind Regards,
Rafael

Works perfectly!


	Download zip.

	Upload object-cache.php file (not memcached folder, only object-cache.php) to wp-content folder (not plugins folder).

	Add define('WP_CACHE_KEY_SALT','RANDOM SALT KEY'); to wp-config.php

	Add 
$memcached_servers = array(
	'default' => array(
		'127.0.0.1:11211'
	)
);


to wp-config.php
	done.


Working Perfectly

WARNING The development of WP-FFPC had been put on hold. 
If you need new features, please send code and pull requests to <a href="https://github.com/petermolnar/wp-ffpc" rel="nofollow ugc">WP FFPC @ Github</a>.
A short why: I developed this plugin in 2010 to support my own site. Right now, as it is, it’s working on a few sites I still maintain for friends and since I don’t need any additional features, I’m not planning to extend it with things I have no real use of. During the past years I’ve received some heartwarming donations – unfortunately the amount never came close to consider the project financially beneficial. I removed the donation links and put it on hold for now.
WP-FFPC is a cache plugin for <a href="https://wordpress.org/" title="WordPress" rel="ugc">WordPress</a>. 
It works with any webserver, including, but not limited to, apache2, lighttpd, nginx.
It can be configured together with <a href="http://NGiNX.org" title="NGiNX" rel="nofollow ugc">NGiNX</a> but use <a href="http://nginx.org/en/docs/http/ngx_http_memcached_module.html" title="memcached plugin" rel="nofollow ugc">memcached plugin</a> directly from the webserver, bypassing PHP.
<h4>Requirements</h4>
This plugin does not kick in right after activation. You have to adjust the setting in Settings -> WP-FFPC and save the settings.*
<ul>
<li>WordPress >= 3.0</li>
<li>at least one of the following for storage backend:
<ul>
<li>memcached with <a href="http://php.net/manual/en/book.memcached.php" title="Memcached" rel="nofollow ugc">PHP Memcached</a> > 0.1.0</li>
<li>memcached with <a href="http://php.net/manual/en/book.memcache.php" title="Memcache" rel="nofollow ugc">PHP Memcache</a> > 2.1.0</li>
<li><a href="http://php.net/manual/en/book.apc.php" title="APC" rel="nofollow ugc">APC</a></li>
<li><a href="http://pecl.php.net/package/APCu" title="APC User Cache" rel="nofollow ugc">APCu</a></li>
</ul>
</li>
<li>PHP 5.3+ is really highly recommended, see “Known issues”</li>
</ul>
<h4>Known issues</h4>
<ul>
<li>errors will not be displayed on the admin section if PHP < 5.3, only in the logs. This is due to the limitations of displaying the errors ( admin_notices is a hook, not a filter ) and due to the lack of proper anonymus functions in older PHP.</li>
<li>If you’re using PHP 5.4+ avoid the APC backend: the plugin with that setup can even make your site slower. Please use APCu or memcached in this case.</li>
</ul>
<h4>Features:</h4>
