Another questions regarding my new server setup. As with the Postgresql setup, different pages describing setting up a Centos LAPP server have differing opinions about PHP versions. The default distro's appear to still be installing PHP5 while some sites instruct on how to install PHP7. I am porting my old server which must be 10 years old, running Fedora 9 and PHP5 onto the new server, so presumably sticking with PHP5 would be the easier option. However, I am looking to give my new server as long a life as possible, so should I instead be looking at PHP7? I have literally thousonds of lines of PHP code on my existing box. How much head ache am I going to have porting into either of the two new platforms? How much difference would PHP5 vs PHP7 be? Opinions please
