The version of PHP that drives your web account can be changed any time from our Request Portal
That setting can be found under your Personal Web account page or from the Manage screen of a Group Web account that you manage.
The currently supported PHP versions will show up in the drop-down menu.
We try to keep a wide range of versions as we know sometimes legacy software takes a while to get updated to the latest versions of PHP.
The drop-down in the request portal is always the most up-to-date list of versions that we support.
