Does Production Require PHP 7?

I believe I read the answer to this somewhere but can’t seem to find it again so sorry to bother the forum.

If I do not use any PHP 7 functions/ constructs, must apps developed in SC9 be deployed ONLY to a PHP 7 server or can still work with PHP 5.6?

Thanks

Production environment for generated applications approved for PHP 5.6 and 7.

So NOT 7.1. Just in addition to jack’s post.

Just curious at this point, but do you specify the target PHP version now on code generation? The reason I ask is that I have my development, staging and production sites on different servers. Not sure if they will all be same PHP version. I hope here is a way to set what my target is. Or does SC make some sort of compatible code depending on what it senses is the PHP version?
