PHP Get Site URL Protocol - http vs https

Question

I ve written a little function to establish the current site url protocol but I don t have SSL and don t know how to test if it works under https  Can you tell me if this is correct   function siteURL          protocol     empty   SERVER  HTTPS     amp  amp    SERVER  HTTPS        off       SERVER  SERVER PORT      443     https        http           domainName     SERVER  HTTP HOST            return  protocol  domainName    define   SITE URL   siteURL        Is it necessary to do it like above or can I just do it like    function siteURL          protocol    http           domainName     SERVER  HTTP HOST           return  protocol  domainName    define   SITE URL   siteURL        Under SSL  doesn t the server automatically convert the url to https even if the anchor tag url is using http  Is it necessary to check for the protocol   Thank you

it s the best solution of https or http use this     lt  php  protocol            site url    protocol   SERVER  HTTP HOST      gt      But can t display https or http  so it only use to link your site content like image  etc   if want to redirect your site in https  add this code in  htaccess file     lt IfModule mod rewrite c gt   RewriteCond   HTTP CF-Visitor    scheme   http    RewriteRule        https   www your-domain com 1  L   lt  IfModule gt      Change www your-domain com with your dowmain name

I know this is an old question but I came across this today since I needed to test for this in my site   It seems the answers above are needlessly complicated   To establish the site protocol  all you have to do is test   SERVER  HTTPS    If the protocol is using HTTPS  then   SERVER  HTTPS   will return  on    If not  the variable will remain empty  For example       test if HTTPS is being used   If it is  the echo will return   SSL test  on    If not HTTPS    SSL test  will remain empty    SSL test     SERVER  HTTPS     echo   lt p gt  SSL test     SSL test   lt  p gt     if  SSL test    true        echo  You  re using SSL     else       echo  You  re not using SSL         You can use the above to easily and cleanly test for HTTPS and implement accordingly

Extracted from CodeIgniter    if     function exists  is https                     Is HTTPS                Determines if the application is accessed via an encrypted         HTTPS  connection                 return  bool             function is https                 if     empty   SERVER  HTTPS     amp  amp  strtolower   SERVER  HTTPS         off                         return TRUE                    elseif  isset   SERVER  HTTP X FORWARDED PROTO     amp  amp  strtolower   SERVER  HTTP X FORWARDED PROTO         https                         return TRUE                    elseif     empty   SERVER  HTTP FRONT END HTTPS     amp  amp  strtolower   SERVER  HTTP FRONT END HTTPS         off                         return TRUE                     return FALSE

I know I m a bit late to this party  but if you much prefer not using   SERVER as it s strongly discouraged  and even deactivated on some PHP frameworks  and you have an apache web server  you can use it s native command thusly  -   protocol   apache getenv  HTTPS      https      http

made a function using the Rid Iculous s answer which worked on my system   function site protocol         if isset   SERVER  HTTPS     amp  amp     SERVER  HTTPS       on       SERVER  HTTPS      1     isset   SERVER  HTTP X FORWARDED PROTO     amp  amp     SERVER  HTTP X FORWARDED PROTO       https    return  protocol    https      else return  protocol    http          Hope it helps

Use this server variable to get the protocol details     scheme     SERVER  REQUEST SCHEME             echo  scheme    it gives http    or https      Note that this server variable is unreliable  For more information take a look at  Is   SERVER   39 REQUEST SCHEME  39   reliable

I know it s late  although there is a much more convenient way to solve this kind of problem  The other solutions are quite messy  this is how I would do it    protocol   stripos   SERVER  SERVER PROTOCOL    https       0    https        http           or even without condition if you prefer    protocol   strtolower substr   SERVER  SERVER PROTOCOL   0 strpos    SERVER  SERVER PROTOCOL                   Have a look at   SERVER  SERVER PROTOCOL

I think the complete func should look like    function siteURL          protocol     http          if             straight         isset   SERVER  HTTPS     amp  amp  in array   SERVER  HTTPS      on   1                        proxy forwarding         isset   SERVER  HTTP X FORWARDED PROTO     amp  amp    SERVER  HTTP X FORWARDED PROTO       https                   protocol    https                  domainName     SERVER  HTTP HOST        return  protocol    domainName      Notes     you should look also for HTTP X FORWARDED PROTO  e g  if proxy server   relying on 443 port is not safe  https could be served on different port   REQUEST SCHEME not reliable

For any system except IIS this is quite enough to define site self URL    siteURL  http   empty   SERVER  HTTPS        s           SERVER  HTTP HOST          or    siteURL  http   empty   SERVER  HTTPS        s           SERVER  SERVER NAME          depends on what you exactly want  HTTP HOST vs  SERVER NAME

Because testing port number is not a good practice according to me  my solution is   define  HTTPS   isset   SERVER  HTTPS     amp  amp  filter var   SERVER  HTTPS    FILTER VALIDATE BOOLEAN      The HTTPSconstant returns TRUE if   SERVER  HTTPS   is set and equals to  1    true    on  or  yes   Returns FALSE otherwise

Here is how I do it     it is a shorthand if else version of Rid Iculous s answer       protocol   isset   SERVER  HTTPS     amp  amp     SERVER  HTTPS        on       SERVER  HTTPS       1     isset   SERVER  HTTP X FORWARDED PROTO     amp  amp    SERVER  HTTP X FORWARDED PROTO        https     https     http

In case of proxy the SERVER PORT may not give the correct value so this is what worked for me -   protocol      empty   SERVER  HTTPS     amp  amp    SERVER  HTTPS       off        SERVER  SERVER PORT      443      SERVER  HTTP X FORWARDED PORT      443     https        http
