| 15 | * which will be executed before any other. Suitable for:
|
---|
| 16 | * 1. Set PHP ini settings using ini_set()
|
---|
| 17 | * 2. Custom session save handler with session_set_save_handler()
|
---|
| 18 | * 3. Any custom integration code. If you use any global variables
|
---|
| 19 | * here, they can be accessed in config.php via $GLOBALS array.
|
---|
| 20 | * It's recommended to use constants instead.
