Different versions for different sites.
WHAT IT ALLOWS
Running one version on your main site and a different one elsewhere in the same account.
WHEN THIS HELPS
An old application you cannot yet upgrade, alongside a current site Testing a new version on one site before moving everything
HOW TO SET IT
The cPanel PHP selector allows setting a version per directory.
WHAT TO BE CAREFUL WITH
Forgetting a directory is on an old version.
Set it deliberately and document it.
WHY IT IS A TEMPORARY MEASURE
An application requiring an old PHP version is unmaintained.
Use the flexibility to buy time, not to avoid the problem indefinitely.
WHAT TO CHECK
After changing versions globally, verify no directory was left behind.
FOR SUBDOMAINS AND ADDON DOMAINS
Each has its own directory, so each can have its own version.
Check all of them.
