Does this also solve the problem when I am trying to use a query string parameter with a + in it? I want to use 'starttimetime' with value '2017-04-05T11:48:59+02:00'. Eventually this is being sent with a space.

I debugged it and this is caused by the Request::getArrayFromQuerystring function that uses parse_str. This decodes the + sign to a space.

Hello,

Will this pull request be merged any time soon ?

I have a similar issues when sending multiple tags (eg. someUrl?tags[]=php&tags[]=unirest). Unirest strips the second parameters resulting in someUrl?tags[]=php.

Thanks!
