Apply consistent security settings to both environments so issues
surface early in development rather than first appearing in prod.
Both environments:
- expose_php=Off — hide PHP version from X-Powered-By
- allow_url_include=Off — prevent remote file inclusion
- open_basedir=/var/www:/tmp — restrict filesystem access
- disable_functions — block shell execution functions unused by the app
- Session: strict_mode, httponly, samesite=Lax, use_only_cookies
Production additionally:
- display_errors=0, log_errors=1
- session.cookie_secure=1 (HTTPS-only)
Removed deprecated sid_length/sid_bits_per_character (PHP 8.5+).
