Environments

You can set the environment of you application and load config items depending on the current environment. It also disables PHP from displaying errors in environments other than development. To set your environment, open index.php, located at the root and change the ENVIRONMENT constant. By default, there is support for a development, test and production environment.

To set your environment, open index.php, located at the root and change the ENVIRONMENT constant. By default, there is support for a development, test and production environment.

+ You may load different configuration files depending on the current environment. + The ENVIRONMENT constant is defined in index.php, and is described + in detail in the Handling Environments + section. +

+ +

+ To create an environment-specific configuration file, + create or copy a configuration file in application/config/{ENVIRONMENT}/{FILENAME}.php +

+ +

For example, to create a production-only config.php, you would:

+ +
    +
  1. Create the directory application/config/production/
    2. +
  2. Copy your existing config.php into the above directory
    3. +
  3. Edit application/config/production/config.php so it contains your production settings
    4. +
+ +

+ When you set the ENVIRONMENT constant to 'production', the settings + for your new production-only config.php will be loaded. +

To make a config file environment-aware, copy the file from application/config/ to application/config/development/, depending on the environment the config file belongs to. You can place the following configuration files in environment folders:

You can place the following configuration files in environment-specific folders:

Note: CodeIgniter always tries to load the config file for the current environment first. If the file does not exist, the global config file (i.e. application/config/) is loaded. This means you are not obligated to place all your config files (but rather the files that change per environment) in an environment folder.

This means you are not obligated to place all of your configuration files in an environment folder − only the files that change per environment.
