Why does compatibility matter?
PHP is a programming language on which the WordPresscode is based. This language runs on the server, and it is critical to keep it updated for security and functionality. Various teams within the WordPress open source project work to both test and fix any issues with new PHP versions so you can update with confidence that the WordPress core software is compatible.
