Migrating from PHP 5.6.x to PHP 7.0.x


PHP 7 is under development


PHP 7.0 is still under development and while it is unlikely to happen, the features and changes noted in this section are subject to change before the final 7.0.0 release. Please double check this migration guide before deploying a stable 7.0 release to production.

Despite the fact that PHP 7.0 is a new major version, efforts were put in to make migration as painless as possible. This release focusses mainly on removing functionality deprecated in previous versions and improving language consistency.

There are a few incompatibilities and new features that should be considered, and code should be tested before switching PHP versions in production environments.
