You have to configure your host to use the updated PHP. Usually, this requires root access to the server.

You should contact the people providing web hosting for you to see if you can get them to upgrade PHP or how you can use a newer version.

If you can't do that, then you should download 1.19 which is an LTS supported till this next April and should work for your version of PHP.
