There always configuration which changes according to application settings. Such settings are database credentials, cache configuration and etc. These configurations are always different for local, test and live application stage.
Because each settings file does not allow configuration to be as per application stage. We can store such configuration as per application stage using environment variable.
Why environment variable
As these configurations are stored as per application stage then why is it called environment variable instead application stage data?
This is because
Nishchay first finds data in environment variable then it looks into stages data.
These data are stored in into their own file in
settings/env directory. File named same as application stage name. For application stage
local file name is
Below is example of how these data can be stored for
local.ini, same as applicable for
; Database name DB_NAME = 'MainDB'; ; Host name where database server is located. DB_HOST = '127.0.0.1'; ; Port number on which database server is running. DB_PORT = 3306; ; Authentication username DB_USER = 'root'; ; Authentication password DB_PASS = 'root';
How to fetch
We can these data using
env shorthand of
getEnvironment. This method accepts two arguments first being variable name and second one is default(Optional parameter). If there's no data for passed variable, the default is returned. BY default this is
$databaseName = getEnvironment('DB_NAME');
