PHP7 compatibility with Symfony3?

Question

With the release of both PHP7 and Symfony3 this week, have Symfony3 been developed with PHP7 in mind?

To put it another way, if we have PHP7 installed and are starting a new Symfony3 project from scratch, do we run the risk of facing migration problems from within the Symfony framework?

Answer 1

PHP 7 is mostly backward compatible with 5.x versions. Most of the changes that are incompatible with previous versions consist of the removal of quirky features anyway. This is usually not the type of stuff SF developers tend to use.

And, yes, SF3 has been developed with PHP7 (and HHVM, by the way) in mind.
