How to find url in php

[LondonBoy]

Hello all,

If my site has two domains, but domain one should point to french which already works.

but domain 2, how can I check the url and if url is let's say domain2.com then add lang=en to the query string.

Thanks

In pusedo code... (don't comment on my spelling... ).

  1. Get the domain name
       - you should be able to use parse_url() for this.
  2. Check the domain to see if it the english or french.
       - possible to use if else statments.
  3. If it is english, redirect 
       - using headers would work...
       - make sure that on the top of the website have a code saying:
              if($lang=="en" || $lang=="fr") {
                   // Do not redirect
              }
            - this is to prevent looping

At least, that's the way I'd think about doing it.

how do I get the domain name

every example of parse_url() on the internet assumes you already have the domain name.

Can anyone help me out?

echo '<pre>';
print_r($_SERVER);
echo '</pre>'; 

look at the variables in there

Thanks

I'll try that out, documentation for parse_url() is horrific!

So $_SERVER is the best approach?

[dniwebdesign]

Now that I look at it yes... the $_SERVER should get the domain name for you... however it will get the domain name for the current domain shown in the top.

after getting the domain name how would I go about appending a language query string appended to the querystring?

$_SERVER['HTTP_HOST']

[LondonBoy]

If I made this code:

$host = $_SERVER['HTTP_HOST'];

if (!isset($lang)) {
if ($host=="www.domain1.com") {
$lang=fr;}
if ($host=="www.domain2.com") {
$lang=en;}
}


From there, how would I append the lang variable in the URL?
There might or might not be a querystring already initiated, so I may start with & or with ?

Would anyone know this?

any1 plz

http_build_query() (or the PHP4 implementation.
Checking for the '?' is easy.

<?php
if(strpos($url, '?') !== false))
{
   // Query string is there. Add a "&"
}
else
{
   // No query string. Add a " ? "
?>
