Need to strip url and leave just host url

Example:
I need to strip this url: www.example.com/dir1/dir2/page.html
to
www.example.com


I'm trying to link to the site analytics page at Compete.com for each result in my search engine
( www.GoLexa.com ). However it will only accept the host url with nothing past the extension.

Here's and acceptable call:
http://siteanalytics.compete.com/www.cnn.com/

This would not be acceptable:
http://siteanalytics.compete.com/www.cnn.com/news.html


Here's what I currently have to make a call to Compete.com, I've stripped off the http:// leaving the url starting with www:
http://siteanalytics.compete.com/".str_replace("http://", "", $val['redirecturl'])."
This works fine as long as there's nothing past the extension.

This is my variable: ".str_replace("http://", "", $val['redirecturl'])."

Thanks,
ED

 

Take a look at the parse_url function:
http://www.php.net/manual/tw/function.parse-url.php

 

The contents of the $_SERVER['SERVER_NAME'] variable might be all that you need.

Hope this helps

 

try this

$url = "www.example.com/dir1/dir2/page.html"
$url2 = explode("/", $url);

echo $url2[0];
