Frustrated by Magento? Then you’ll love
An Interesting Challenge for folks Using Magento 1 and PHP 7
Magento 1 doesn’t officially support PHP 7, but the changes needed to Magento’s core code to get this working aren’t too strenuous, and even third party extensions can be patched/modified to make this work.
Whatever interesting here is the de-facto standard practice of using Magento Connect’s version compatibility features to say “Any version of PHP 5.x that’s ever released”. It sounds like Magento Connect won’t install most packages in a PHP 7 system due to the settings extension vendors originally used, back when the idea of a PHP 6 or 7 seemed like a far off dream.
