steps:
open the file
index.php
under the codeigniter 4 application's public path/root/ci4/public
.load the
.env
file of the react application just before the line of code$app->run();
in the file/root/ci4/public/index.php
:
// ...
// load environment settings from .env file into $_server and $_env
$envpath = rootpath . ".." . directory_separator . "react";
$envfilename = ".env";
if (is_file($file = $envpath . directory_separator . $envfilename) && is_readable($file)) (new \codeigniter\config\dotenv($envpath, $envfilename))->load();
// ...
where:
$envpath
- represents the directory path of the "react application's".env
file. it's assumed that it resides under/root/react/.env
$envfilename
- represents the "react application's".env
file name.\codeigniter\config\dotenv(...)->load()
- this method is the one responsible for loading the.env
file and processing it so that we end up with all settings in the php environment vars (i.e.getenv()
,$_env
, and$_server
).
extra notes:
a.
if a
.env
variable already exists in the environment, it will not be overwritten. - environment variables and codeigniter
this means that an environment variable defined under /root/react/.env
won't overwrite a similar one defined under /root/ci4/.env
.
b.
warning: note that your settings from the
.env
file are added to environment variables. as a side effect, this means that if your codeigniter application is (for example) generating avar_dump($_env)
orphpinfo()
(for debugging or other valid reasons) your secure credentials are publicly exposed. - environment variables and codeigniter
