I have an mvc app which uses composer on a Centos7 web server which was upgraded to php70w.
Does this mean composer and its modules should also be upgraded and if so, how?

# composer install --dry-run
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - This package requires php ~5.4 but your PHP version (7.0.9) does not satisfy that requirement.

It looks like a requirement for ~5.4 would allow PHP5.4, PHP5.4.x, PHP5.5 but not PHP7.x.  Using the tilde tells composer to restrict the major version number to 5, and to set the minimum to 5.4.

I can't tell what your specific PHP requirements are from where I sit.  There are known breaking changes between 5.4.x and 7.0.  These can be found by walking through the changelog (see also).  If you determine that PHP7 is OK for your application, your expression might look something like this:

>=7.0-stable
