/**
|
|
* Billing config loader
|
|
*
|
|
* Load order:
|
|
* 1. modules/billing/includes/config.inc.php — always loaded first; contains billing-specific
|
|
* settings (PayPal credentials, SITE_BASE_URL, SITE_BACKGROUND, SITE_DATA_DIR, backup
|
|
* retention, and default DB settings for standalone installs).
|
|
* 2. <panel_root>/includes/config.inc.php — read via regex (no side-effects) when the
|
|
* billing module is installed inside a GSP panel tree. DB variables extracted from the
|
|
* panel config override the billing config DB variables in memory so that the module
|
|
* always connects to the active panel database.
|
|
*
|
|
* Panel-child detection:
|
|
* Walk up from modules/billing/includes/ looking for the pattern
|
|
* <ancestor>/includes/config.inc.php that contains the GSP panel DB variables
|
|
* ($db_host, $db_user, $db_name, $table_prefix). Stop after six levels.
|
|
*
|
|
* Config sync:
|
|
* If the panel config DB variables differ from the billing config file on disk, the loader
|
|
* updates only the DB variable lines in billing/includes/config.inc.php so that subsequent
|
|
* page loads (and standalone tools) always see current credentials. The sync only runs when
|
|
* the file is writable. If it cannot write, a non-fatal admin-visible warning is set in
|
|
* $billing_config_warning.
|
|
*
|
|
* Standalone installs:
|
|
* When no panel config is found the billing config is used as-is; standalone mode is fully
|
|
* supported.
