Cmemcache With Igbinary

So I already had memcached installed on my system with the pecl extension, then today I looked into and installed the igbinary serializer. When I run phpinfo(), both are in there, but under memcached: igbinary support it says No.

When configuring the CMemCache component in the config, I have the ability to set the serializer to whatever I want. Will setting this to:


    'igbinary_serialize', 'igbinary_unserialize'


work? Or do I need memcached to say support is Yes?

Also, in the config do I include the brackets after igbinary_serialize() in the config?
