Failed to parse dotenv file due to unexpected whitespace

Hi!

This issue is related to #520, and I think the root problem can be AWS fault, BUT, maybe the repo admin can help us to solve this problem here. Or maybe help us to reach out AWS support team.

About 3 days ago, using AWS Codebuild in a code pipeline which builds and deploys my laravel project on AWS ECS, I suddenly faced an error:

#22 8.200 Fatal error: Uncaught Dotenv\Exception\InvalidFileException: Failed to parse dotenv file due to unexpected whitespace. Failed at [--with-curl --with-password-argon2 --with-pdo-pgsql --with-libedit]. in /var/www/html/vendor/vlucas/phpdotenv/src/Loader/Parser.php:119

Nothing on my code was changed. All things was working and now it's not.

After digging a bunch of possible causes, and having 100% sure that my env vars was not the problem, I found out the error cause:

I'm usgin AWS Codebuild and they have a place to add env vars on the console. like this:

and they have a thing called Buildspec, where you writes down commands to build your project and you can do a command called printenv > .env and then a docker-compose build to create the docker image like this:

ok my .env file is created on the fly, BUT, AWS inject a bunch of env vars on my .env file, that I never have originally defined on my project and two of these vars is causing the problem:

this not work (the way AWS injected these vars)

PHP_BUILD_CONFIGURE_OPTS=--with-curl --with-password-argon2 --with-pdo-pgsql --with-libedit
PYTHON_CONFIGURE_OPTS=--enable-shared --enable-loadable-sqlite-extensions

Because they are writed this way, and not enclosed by double quotes like this:

If AWS had written the variables this way, it would have worked

PHP_BUILD_CONFIGURE_OPTS="--with-curl --with-password-argon2 --with-pdo-pgsql --with-libedit"
PYTHON_CONFIGURE_OPTS="--enable-shared --enable-loadable-sqlite-extensions"

So, I'm pretty sure that AWS should enclose this values in double quotes, but we have no control on this.

And I'm wondering two possibilities:

Let's change (if it's possible) the way phpdotenv reads these values and accept that the value can be writed this way too OR
Let's try to reach out the AWS Codebuild team and open a issue to them, showing the problem and asking to put these values in double quotes (I think this is really hard to accomplish)

What can we do?

Thanks!
