we have developed our application in Slim Framework 2.0 with Php 7.1. Now We are planning to Upgrade Php Version 7.1 to 7.4.
I have checked the Php Migration Documentations, There are many functions and components they have deprecated and they have updated the response/returns of the functions. Please refer the below links for the Php migration documentation from Php7.1 to 7.4 https://www.php.net/manual/en/migration74.php https://www.php.net/manual/en/migration73.php https://www.php.net/manual/en/migration72.php
So can you please check and let me know from Slim Framework 2.0 perspective will there be any impact, if I upgrade to php7.4? Or do I need to Upgrade my Slim Framework as well. if I need to Upgrade my Slim Framework then to which version do I need to upgrade
