PhP Help!

I am going to throw this out here to see if there might be anyone who could help me.

I have been using the RPG web profiler software for the last 10 years. It was a project started back in the day and others have contributed to it.

https://sourceforge.net/projects/rpgwebprofiler/

The challenge is that the last level of development on the PhP web software only works to PhP 5.6, and my server admin says we need to upgrade to PhP 7.x

Met result is the profiler will no longer work. We have a lot of player characters in our database and I would hate for everyone to lose their characters. I know how to work in PhP to create sheet templates, but I do not know how to correct the programming that works in 5.6 to 7.x.

I was wondering if anyone out there knew how to program in PhP and would be willing to help. I am willing to offer payment for services, but it would have to be agreed upon at the onset and within a budget. Since it is freeware, it would be cool to work with someone that wants to take this project to the next level.

I present some PC sheets below to illustrate what the profiler does for those unaware. Not all of these sheets directly relate to Trek, but there is a number of templates for different character types. I know, too, that there are a lot of gamers on this board and hope that someone in this group might be able to help.
