The other day a friend of mine was using google-auth-library-php
in combination with google-cloud-php-pubsub and wanted to set the
path for the google credentials file via GOOGLE_APPLICATION_CREDENTIALS in .env.
So we figured that this did not work anymore in the newer version of dotenv (see commit in 4.3)
the default value for use_putenv changed to false. And in symfony 5 there was a breaking change to switch use_putenv
from true to false (see the putenv deprecation pull request.
The suggestions to activate use_putenv again in Dotenv via calling
$dotenv->usePutenv(true);
But it shows the reason why it goet deprecated and removed in symfony:
Beware that
putenv()is not thread safe, that's why this setting defaults to false
But in symfony you don't have access to the dotenv instance and cannot preinitiate it. Some days later by accident
I found that you can set runtime options for symfony runtime and that they support use_putenv.
So if you edit your index.php and bin/console files before loading the autoload runtime from
require_once dirname(__DIR__).'/vendor/autoload_runtime.php';
to:
$_SERVER['APP_RUNTIME_OPTIONS']['use_putenv'] = true;
require_once dirname(__DIR__).'/vendor/autoload_runtime.php';
you can change some of the runtime options. See SymfonyRuntime::_construct for all the available options.
For google auth php library I created a pull request to change it's usage from getenv to $_ENV.
