Well said. If it is not possible to have a single codebase that runs in

Of course you can have a single codebase running both on PHP5 and
PHP7, unless you want to use PHP7-only features.
It may be true right now, but it is not inevitable. There are certain
behaviour or syntax changes that could, theoretically, require the same
feature to be written differently in the two versions.
Luckily, such changes are rare, and are usually spotted and avoided (as
with the change to DateTime typehinting mentioned recently), but it's
not something that goes without saying.
