I have created some input-wrapper-functions for php (get, post, get_post, session, cookie): https://gist.github.com/voku/7c995ed2e19d78a164e2

########
usage: set cookies
########

set_cookie(‘foo’, ‘bar’);

########
usage: get cookies
########

echo cookie(‘foo’, FILTER_SANITIZE_STRING); // bar
echo cookie(‘foo’, FILTER_SANITIZE_NUMBER_INT); //

########
usage: remove cookies
########

delete_cookie(‘foo’);
