Just did that. The beginning of the login looks just the same. Things  
start to differ with command 37.
In PHP 5 it reads (I replaced the folder names which contained actual  
names with "NameXX"

The same passage in PHP 7 reads:

  It seems to not list subscribed folders (or any folders for that  
matter) with PHP 7. I tried turning off folder subscription, but that  
didn´t help.
