// ─── DB-backed system settings with file-based cache ─────────────────────────
|
|
//
|
|
// Settings live in the `system_settings` table (key→value). To avoid a query
|
|
// on every page load, the full set is cached as a PHP array literal under
|
|
// config/cache/settings.cache.php — read via require, served from opcache
|
|
// in memory. The cache is invalidated (file deleted) on every db_update_setting().
|
|
//
|
|
// Public API:
|
|
// setting($key, $default = null) — cached read
|
|
// settings_all() — cached array
|
|
// db_get_all_settings($pdo) — bypasses cache
|
|
// db_update_setting($pdo, $key, $value, $userId = null) — UPSERT + invalidate
|
|
//
|
|
// $pdo is read from the global scope only by db_*() helpers; setting() and
|
|
// settings_all() never touch the DB once the cache exists.
