Question

I have two urls - biothoughtblog.co and playfight.co. The first is forwarding to the second and masking is used. I am using this

<?php
function curPageURL() {
 $pageURL = 'http';
 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
 $pageURL .= "://";
 if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
 } else {
  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
 }
 return $pageURL;
}
?>

<?php
  echo curPageURL();
?>

on the page http://www.biothoughtblog.co/test.php - however, it echoes the real URL which is http://www.playfight.co/test.php. I need it to echo the URL that is in the address bar. I know very very little Javascript - is it what I need to be using here?

Thanks a lot.

P.S Oh, and the purpose is to run the same website under two different domains and different branding (logo, etc).

Answer 1

That's because http://www.biothoughtblog.co/test.php is framing http://www.playfight.co/test.php.

<frame src="http://www.playfight.co/test.php" frameborder="0" />

PHP has no way of knowing that it is loaded inside a frameset, and how to get the URL of the parent frame.

You want to avoid using the "masking" feature of your registrar or DNS provider. Point the biothoughtblog.co domain to the same hosting server, ensure that your hosting account is setup for both domains. Then biothoughtblog.co wil be hitting your website directly, and PHP will know what it is.

Answer 2

You don't need to do anything in PHP to run the same website under two different domains.

If you are using apache, open your conf file, locate your virtual host config and add a serverAlias.

Example:

<VirtualHost *:80>
    DocumentRoot "/var/www/html"
    ServerName biothoughtblog.co
    ServerAlias playfight.co
    <Directory "/var/www/html">
        AllowOverride All
    </Directory>
</VirtualHost>
