Variable, Get Url???

Ok this is my problem.

I have a script I am using as an include in many sites. It pulls info from a database and displays ads. Now every site that this is displayed on has an ad in the database and I dont want anyones ads showing on their own site.

I wrote this.

##$current = $_SERVER["HTTP_HOST"];
$current = $_SERVER['PHP_SELF'];

$lin = mysql_query("SELECT * FROM link order by id asc", $link) or die ("query 1: " . mysql_error());
echo '<li><h2>LinkWork</h2>'
. '<ul>';
while ($li = mysql_fetch_array($lin)) {
if ($current == $li['base'])
{
echo '';
}
else
{
echo '<li><a href="'.$li['web_url'].'" alt="'.$li['alt_tag'].'">'.$li['display'].'</a></li>';

}
}

The column base, is the base of a url eg. digitalpoint.com

So that is what I need to find, a php variable that gives me the current pages web address, but only up to the end of the com or org.

 

Use

parse_url()

PHP:

function.

 

I assume from the comment that HTTP_HOST isn't enough? There's no server variable as such containing a full URL but you can put it together yourself.

$currentURL = 'http'.(empty($_SERVER['HTTPS'])?'':'s').'://'.$_SERVER['HTTP_HOST'];

PHP:

If you want to go further than the hostname, you'd just need to add the REQUEST_URI

 

Maybe add more dir url

Above code . dirname($_SERVER['PHP_SELF']) 

PHP:
