getenv(ENVIRONMENT VARIABLE) gets nothing-CodePudding

Before uploading my project to Github, I wanted to hide my API key using an environment variable.

I added this line of code inside .env file

API_KEY=MY_API_KEY

but when I call API_KEY in my PHP file,

$apiKey=getenv('API_KEY');
print_r($apiKey);

It shows nothing. And my site crashes because code didn't get the API key.

I tried using SetEnv on the bottom of the httpd.conf file.

SetEnv API_KEY=MY_API_KEY

but this still doesn't work. print_r() prints nothing. Just nothing... What am I doing wrong?

Should the .env file be located in the same location as the PHP file? I am using windows and Xampp Apache is my web server.

As IMSoP mentioned in comment, I had to do something to force PHP to read my .env file and I solved this issue by installing phpdotenv. https://github.com/vlucas/phpdotenv This package makes available to read .env file.

if(file_exists(dirname(__DIR__) . '/vendor/autoload.php')) {
    require_once dirname(__DIR__) . '/vendor/autoload.php';
    $dotenv = Dotenv\Dotenv::createImmutable(dirname(__DIR__));
    $dotenv->load();
}

This method should have worked, except you have used the wrong syntax. There should be no = between the key/value pairs. The above would have set an environment variable called API_KEY=MY_API_KEY (instead of API_KEY) and assigned an empty string!

It should simply be:

SetEnv API_KEY MY_API_KEY

After changing httpd.conf you would need to restart Apache.

Alternatively, add the directive to a .htaccess file in the document root. (Or relevant subdirectory.)
