Codeigniter - switch between environments
Constant: A constant is an identifier (name) for a simple value. As the name suggests, that value cannot change during theexecution of the script
So there is no scope to redefine the value of ENVIRONMENT constant as it is already defined. You can use another constant name [except ENVIRONMENT or the other which are already used by codeignitor] or preferable a variable to maintain your country related version.
In your root folder there is an file call index.php(image attach below)
In here if you define 'development', It will show your errors on your Codeigniter framework.
For example if database error occurs it shows this kind of error
So this you can check whats wrong and all.
You can test it by define to
testingorproduction. So that you will only get blank page instead of Error Details.
