php - combine option field results to text field -

I tried to find it and this is probably a simple solution, but I can not understand how an option field To combine the text field in HTML / php / js In fact, the user needs to choose whether he is http or https and then type in the domain. It should be presented as a single variable via _GET.

  & lt; Select & gt; & Lt; Option value = "http: //" & gt; Http: // & lt; / Options & gt; & Lt; Option value = "https: //" & gt; Https: // & lt; / Options & gt; & Lt; / Select & gt; & Lt; Input class = "span4" id = "domain" name = "domain" type = "text" & gt; & Lt; Button class = "btn btn-success" type = "submit" & gt; Submit & lt; / Button & gt; & Lt; / Form & gt;   
 Any input will be appreciated.   
 
 
 I'll combine them after submitting ...  
 HTML page ( You need your  SELECT  name):  
  & lt; Select name = "type" & gt; & Lt; Option value = "http: //" & gt; Http: // & lt; / Options & gt; & Lt; Option value = "https: //" & gt; Https: // & lt; / Options & gt; & Lt; / Select & gt; & Lt; Input class = "span4" id = "domain" name = "domain" type = "text" & gt; & Lt; Button class = "btn btn-success" type = "submit" & gt; Submit & lt; / Button & gt; & Lt; / Form & gt;   
 PHP page:  
  $ type = $ _GET ['type']; $ Name = $ _GET ['domain']; $ Composite = $ type $ name;             P> 
 Of course. As  $ name  like  $ type  and  www.example.com  then the variable Must be a value of  $ United  for  https://www.example.com
