$memcache->set('key', $mydata, false, 100); //add it to memcached server

For example, CentOS does not have Memcached in its repository, so you should use RPMForge (http://wiki.centos.org/AdditionalResources/Repositories/RPMForge) or other repo.
BTW, when you use only one server (localhost), it’s better to use APC or XCache because they don’t open TCP connection.
This post is over-explained,rightly said Baby steps. in reality however you need 4 steps Max.
Cheers !!
really useful! thanks!

xjRrB3 Excellent article, I will take note. Many thanks for the story!
Nice article.
I would recommend using the newer Memcached PHP library instead of the older ‘Memcache-without-the-d’lib. The newer one is a lot faster and manages connections much faster.
The older library still shows up first in Google results, so here’s the link:
