Quick Answer: What Does $config Do?

? Simple Answer

$config is like a settings box that holds application settings like debug mode, timezone, session config, etc.

NO, it doesn't overwrite anything! It's completely separate from $fallbacks and .env.

? Three Separate Storage Boxes

????????????????????????
?    $fallbacks        ?  Box #1: Just site_path & domain_name
?  - site_path         ?         (backup if .env missing)
?  - domain_name       ?
????????????????????????

????????????????????????
?     $config          ?  Box #2: General settings
?  - debug             ?         (used by app internally)
?  - timezone          ?
?  - session [...]     ?
?  - cache [...]       ?
?  - security [...]    ?
????????????????????????

????????????????????????
?    .env file         ?  Box #3: Environment config
?  SITE_PATH=...       ?         (HIGHEST PRIORITY)
?  DOMAIN_NAME=...     ?
?  DB_HOST=...         ?
?  etc...              ?
????????????????????????

They NEVER conflict! Each has its own purpose.

? Where Each is Used

$fallbacks Used By:

Config::getSitePath()      ? Checks .env, falls back to $fallbacks
Config::getDomainName()    ? Checks .env, falls back to $fallbacks

$config Used By:

Config::get('debug')       ? Gets from $config
Config::get('timezone')    ? Gets from $config
Config::get('session.name') ? Gets from $config
Config::set('debug', false) ? Changes $config

.env Used By:

Environment::get('SITE_PATH')    ? Gets from .env
Environment::get('DB_HOST')      ? Gets from .env
ConfigManager::get('app.debug')  ? Gets from .env

? Real Example

// Startup sequence:

// 1. Application loads .env
Environment::load();  // Box #3 populated

// 2. initConfig() runs
date_default_timezone_set(self::get('timezone', 'UTC'));
//                        ? Gets 'UTC' from $config (Box #2)

// 3. User calls getSitePath()
Config::getSitePath();
// ? Checks .env (Box #3) first
// ? If not found, uses $fallbacks (Box #1)

? Bottom Line

$config is NOT overwriting anything!

It's just a storage array for: - Debug mode - Timezone - Session settings - Cache settings - Security settings

Used internally by Config::get() and initConfig()

Think of it as the "general settings" box, while: - $fallbacks = "path/domain backup" box - .env = "environment values" box

All three work together without conflicts! ?
