Many thanks for that work @peter279k!

I left a few nitpicks, but looks pretty good otherwise. I'll do a release shortly after this is merged

[theofidry]

why removing this? I would actually add --no-progress --no-suggest

[peter279k]

Do you mean replace --no-progress --no-suggest with --no-interaction --prefer-dist ?

[theofidry]

No I mean adding it as well, sorry for not being clear enough

[peter279k]

It's okay. I will add this options back.

[theofidry]

No need for a changelog, the releases contains the changelog for now :)

[peter279k]

Oops! It's my fault. I will remove this.

I wonder why this library needs to be used in PHP 7 and above, where file_get_contents function was already fixed to work with SSL urls?

[theofidry]

No you don't need it in PHP 7+. It's good to keep the support for it as a lib may be using it and support PHP 5.x and 7.x, but a PHP 7+ only doesn't make sense.

Many thanks @peter279k

[aik099]

I see, thanks. I'm kind of CURL guy, never used file system functions to access URLs of any kind.

[peter279k]

Sometimes I maintain the old legacy system and need the file_get_contents to handle the HTTP.
And I know the curl (even Guzzle) is better than using this.
Thank you for @theofidry again.

[theofidry]

Sure, but this allows you to query a URL without having the curl extension or Guzzle installed so it's a pretty good solution for minimal requirements :)

That said I wouldn't recommend to replace all your clients by it, it's for very specific usages.
