Codeigniter 4 Environment

Now Lets, Talk about Codeigniter 4 Environment and its Variable. Actually, Codeigniter has 3 different environments:

  1. Production mode: Its stops all display an error and help the user to make the application live.
  2. Development mode: Its works on when the application in development mode or Developer working on it.
  3. Testing mode: As we all know testing mode is next stage after the development completed.

How we set or change the Codeigniter 4 Environment?

Developers often desire different system behaviour depending on whether an application is running in a development or production environment.

For example, verbose error output is something that would be useful while developing an application, but it may also pose a security issue when “live”. In development environments, you might want additional tools loaded that you don’t in production environments, etc.

So, there are many ways to handling environment variables but here are two simple and quicks ways:

1: ENV FILE: You can change the environment variable through the .env file founded in your base directory. The simplest method to set the variable is in your .env file.

CI_ENVIRONMENT = development

2: Index.php: You can change the environment variable through index.php in the root directory. The simple and used by most of the developers.

define("ENVIRONMENT","development");

3: Apache: This server variable can be set in your .htaccess file or Apache config using SetEnv.

SetEnv CI_ENVIRONMENT development

4: Nginx: Under Nginx, you must pass the environment variable through the fastcgi_params in order for it to show up under the $_SERVER variable. This allows it to work on the virtual-host level, instead of using env to set it for the entire server, though that would work fine on a dedicated server. You would then modify your server config to something like:

 
server {  
   server_name localhost;    
   include     conf/defaults.conf;     
   root        /var/www;     
   location    ~* \.php$ 
          {         
             fastcgi_param CI_ENVIRONMENT "production";         
             include conf/fastcgi-php.conf;    
        } 
}

What is PHP Constant?

PHP Constants are similar to variables, holding information to be accessed later, except that they are what they sound like—constant. In other words, once you have defined one, its value is set for the remainder of the program and cannot be altered. Read more about PHP Constants.
