PHP: Display Domain Name

BobbyDouglas · #1 27-Nov-2003, 12:21

How would I display the domain name of the page I am at. Lets say it it www.desilva.biz/something.html and I want to display desilva.biz. Exactly like that. No www, or http:// included.

I have tried

Code:

<?php echo htmlentities( $_SERVER['REQUEST_URI'] ); ?>

but it does not quite work.

The code above displays a frontflash '/'. And not the domain.extension.

things like

PHP Code:


$_SERVER['HTTP_HOST'];$_SERVER['SERVER_NAME'];

will display the hostname without http://

but sometimes it include www.
but a simple

PHP Code:


$hostname = str_replace('www.', '', $hostname);

will fix that.

and then you can just append the request uri

Well, I put

PHP Code:


<?
$_SERVER['HTTP_HOST'];
$_SERVER['SERVER_NAME'];
$hostname = str_replace('www.', '', $hostname);
?>

And it does not work. http://www.mrbobdouglas.com/new/index.php

Try this, which is a full script

PHP Code:


<?php$hostname = $_SERVER['SERVER_NAME']; $hostname = str_replace('www.', '', $hostname); echo $hostname . htmlentities($_SERVER['REQUEST_URI']);?>

which displays

Code:

allowee.no-ip.com/test.php

on my box

Still does not show up for me. http://www.mrbobdouglas.com/new/

Also, I would rather just display the domain name, and not the full path to the page.

When someone signs up for a hosting account, they will automatically get the files that belong in their account, I want the index file to read 'This is the new home of [DOMAIN NAME]'

Like Allowee has already said, $_SERVER['SERVER_NAME'] is probably your best bet, however the super global array $_SERVER is only available to a PHP script in the newer versions of PHP...

If you want to troubleshoot this 'issue' yourself, just bring up a phpinfo and go through the values under the PHP Variables table on the page...

BobbyDouglas · #7 29-Nov-2003, 01:21

This is what finally works for me

PHP Code:


<?php
$hostname = $_SERVER['SERVER_NAME']; 
$hostname = str_replace('www.', '', $hostname); 

echo $hostname;
?>

Thanks for the help guys

So sorry for needing to bump this thread but will this code also work for a subdomain?

I want to use it on 404 error pages. For example,

subdomain.domain.com/wrong_page

is an invalid url. It will redirect to, for example, domain.com/404.html

Can I display to the visitor that he might want to check out subdomain.domain.com to find what he wants?

Can you please provide a simple script? Thanks!
