Hey there - this question is a bit odd, but due to various reasons, we are just getting around to updating our server from PHP 5.4 to PHP 7.1.
With this change of course comes verifying that we won’t break anything during this update - which mostly seems to be a nonissue. However one point of possible concern is our infusionsoft SDK. I looked through the changelog, and we have been using the same SDK for many years now, which looks like the last change was in 2009.
This has functioned without any issues for all of this time, but this update to PHP is fairly considerable, and I am worried that it would break a lot of currently existing functionality. We are obviously looking to update to the newest SDK as well, however the newest php SDK isn’t compatible with our current version of PHP, so we’re looking to see if there are any known reasons for the old SDK to not function on the newer PHP (7.1), at which point (once it is updated) we can update to the newest SDK.
If there is somewhere within the SDK files I can get an exact version number or anything, I can definitely do so, but for now all I can say is that this is the last change: 2009-09-05
