Cursor Rules for PHP: 6 Rules That Stop AI From Writing Legacy PHP in 2026

Cursor Rules for PHP: 6 Rules That Stop AI From Writing Legacy PHP in 2026 Cursor writes PHP fast. The problem? It writes PHP like it's 2012 - mysql_* functions, no type declarations, $result variables everywhere, raw $_GET in SQL queries, god classes with 800 lines, and echo statements instead of proper templating. Modern PHP (8.2+) is a different language. It has union types, enums, readonly properties, named arguments, fibers, and match expressions. But Cursor doesn't know that unless you tell it. You can fix this by adding targeted rules to your.cursorrules or.cursor/rules/*.mdc files.
