Am upgrading my magento1.9 site to php version 7.4. I got array_key_exists is deprecated in 7.4 version. In my magento site how to change that function. Some one says use isset or property_exists. How to use this and which one is better.

  • By default Magento1.9 supports up to Php7.2x versions. If you are trying to use Php7.4 it will require more efforts – Mukesh Sep 16 '20 at 13:30
