Sometimes we have content that is specific to a certain country and we only want to show, or hide, it for visitors from that country. Or maybe we want to change some of the language used on a page to cater to different cultures to improve our targeted marketing strategies. We can do this easily with the PHP function below. Once we get the information we need, using a few conditionals will allow you to show, hide or change content depending on where your visitor is from!
