Perhaps you are working in a autoloading namespaced environment [psr-0], try \Memcached wherever you are using it. — moonwave99

php5-memcache and php5-memcached aren't installed. the "rc" in the dpkg output means, that the packages have been uninstalled, and that the configuration has been kept. — Pierre

dpkg -l | grep php5 indicate that module is not install

ii means 'It should be installed and it is installed' whereas

rc means 'It's removed/uninstalled but it's configuration files are still there'

Fatal error: Class 'Memcached' not found

the library might be missing, you can manually include the missing php_memcache into the ext folder
