I'm following the tutorial for symfony installation, but an error occurs when executing it
[GuzzleHttp\Exception\RequestException]
Error creating resource: [message] fopen(https://get.symfony.com/symfony.version): failed to open stream: Unable to find
the socket transport "http" - did you forget to enable it when you configured PHP?
