why this error is coming in php cs

I am running this phpcs command to check one file . I am getting this error.

ubuntu@myip:/var/www/ryapi$ phpcs -n content.php

When migrating to the PHP 5.3 comments in ini files are no longer allowed to start with the #.

Go into /etc/php5/cli/conf.d/mcrypt.ini and use ; instead of #, this is a default error in the latest ubuntu (5.3.2-1ubuntu4.7).

Or set your error settings in PHP to ignore deprecated notices like this

error_reporting(E_ALL  &~ (E_STRICT|E_NOTICE|E_DEPRECATED));
