Configuring options in the bootstrap file
|
|
-----------------------------------------
|
|
|
|
For each application in Yii there is at least one bootstrap file: a PHP script through which all requests are handled. For web applications, the bootstrap file is typically `index.php`; for
|
|
console applications, the bootstrap file is `yii`. Both bootstrap files perform nearly the same job:
|
|
|
|
1. Setting common constants.
|
|
2. Including the Yii framework itself.
|
|
3. Including [Composer autoloader](http://getcomposer.org/doc/01-basic-usage.md#autoloading).
|
|
4. Reading the configuration file into `$config`.
|
|
5. Creating a new application instance, configured via `$config`, and running that instance.
|
|
|
|
Like any resource in your Yii application, the bootstrap file can be edited to fit your needs. A typical change is to the value of `YII_DEBUG`. This constant should be `true` during development, but always `false` on production sites.
|
|
|
|
The default bootstrap structure sets `YII_DEBUG` to `false` if not defined:
|
|
|
|
```php
|
|
defined('YII_DEBUG') or define('YII_DEBUG', false);
|
|
```
|
|
|
|
During development, you can change this to `true`:
|
|
|
|
```php
|
|
define('YII_DEBUG', true); // Development only
|
|
defined('YII_DEBUG') or define('YII_DEBUG', false);
|
|
```
