Also a PHPINIDir directive is useful, as you'll likely have a slightly
different config between the two versions, such as different loadable modules.
Probably more relevant on Windows, though - you'll need a different
extension_dir. On Unix there's more of a tendency to compile the extensions
statically into PHP.
