Config Reference (config.php)

This document explains what each config value is used for at runtime.

ADMIN_EMAIL (your specific question)

ADMIN_EMAIL is the fallback recipient address for internal admin notifications.

Primary recipients come from each admin account in data/admins.json (email field). The fallback is used only when no valid admin account email is available.

Notification scope:

• New reservation created (sendReservationEmails() in includes/functions.php)
• New backorder created (sendBackorderEmails() in includes/functions.php)

It is not used for customer login, admin login, password reset, or contact form logic.

Important notes

• ORDER_HISTORY_COOKIE_SECRET should be a long random value; changing it invalidates old browser history cookies.
• SITE_URL should match the real subpath where the app is served. If wrong, links/assets/cookies may break.
• In this codebase, admin login data is read from data/admins.json (ADMINS_FILE).
  The ADMIN_USERS block is currently a legacy reference in comments/sample config, not active runtime auth.
