Error after it:

It seems you've merged in your apt file wheezy and stretch releases of debian. Try removing the last line of your file :

deb http://http.us.debian.org/debian/ wheezy main contrib non-free

and then try an apt-get update command. Then you could try to install php7.

But be aware that if you're starting from an wheezy install, you must upgrade it to stretch before trying to install php7.0
