mapserver - How compile/install php-mapscript on Ubuntu 16.04

I need to upgrade from Ubuntu 14.04 to 16.04 but php5 is not officially supported on Ubuntu 16. I install php5.5 by ondrej repo https://askubuntu.com/a/756186/483814
but when I try to install php5-mapscript on it i get error :

root@ubuntu16:~# apt-get install php5-mapscript
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package php5-mapscript is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'php5-mapscript' has no installation candidate

Therefore i try to compile and install php-mapscript from scratch but i don't find any updated and working manual.

So if somebody done it before or have general knowledge about mapserver compilation or if know how to install it from repositories please help.

Thanks to @ThomasG77 i did compile and install php5-mapscript of Mapserver7.0.2 compiled and got loaded successfully:

The manual is based on mapserver general compile documentations: http://www.mapserver.org/installation/unix.html#compiling

   sudo apt-get update
   sudo apt-get install php5.5

3. 
   

   install cmake

   
   

   sudo apt-get install cmake
