On the Developer Drive site they've posted an article for all of the WordPress users (and other curious folks) about the impact PHP 7 will have on the current WordPress system.
It’s no big secret now that PHP 7 is just on the horizon, and with that development comes questions on how it affects sites that run on WordPress. PHP 7 is a massive update to the server-side web development language called PHP, yet it’s also going to have an impact on any PHP-powered CMS like Drupal, Joomla and Magento.
They go through some of the major changes in PHP 7 and talk briefly about what kind of effects they'll have on those running this popular CMS including:
- Performance upgrades
- New and improved operators
- Continuous 64-bit support
- Anonymous class support
They recommend that you keep an eye out for messages from your host that they might be upgrading, backing up your site to prevent loss and update your plugins/themes prior to any PHP 7 switch over.
