Message:

Well, I'm trying to use a env var value in PHP 7.2 something like this

$var1 = getenv('AWS_REGION');

[some code bla bla bla]

echo $var1;

but returns this

 Expected string, but got bool(false)

Even I do echo the var and nothing happens

echo getenv('AWS_REGION');

So, in console in console print the variable and returns the value

echo $AWS_REGION

> us-east-2

I have tried everything : getenv, $_SERVER, etc. and nothing works. I'm not sure if I'm missing something.

My Answer:
It seems like the environment variable 'AWS_REGION' is not set or accessible in your PHP environment. Here are a few things you can check and try to troubleshoot the issue:

1. Make sure that the environment variable 'AWS_REGION' is actually set in your system. You can check this by running the command `echo $AWS_REGION` in your console. If it doesn't return anything, then the variable is not set.

2. If the variable is set in your system, make sure that your PHP script has access to it. Sometimes, the environment variables set in the console may not be accessible in the PHP environment. You can try setting the variable directly in your PHP script using `putenv('AWS_REGION=value')` before calling `getenv('AWS_REGION')`.

3. Check if there are any typos or case sensitivity issues in the variable name. Environment variables are case-sensitive, so make sure you are using the correct case when accessing them in PHP.

4. If you are running your PHP script in a web server environment, make sure that the server configuration allows access to environment variables. Some server configurations may restrict access to environment variables for security reasons.

By checking these points and troubleshooting the issue, you should be able to successfully access and use environment variables in your PHP script.
