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


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
