Little help please

[BRUm]

Hi,

I have this snippet:

// Returns array of vals. Ex: array("www", "example", "com");
     $host = explode(".", $_SERVER['HTTP_HOST'], 2);

   // or to pass in a supplied host
    function parseDomainName($host) {
        $pHost = explode(".", $host, 2);
        return $pHost[1];
    }

// loop through the link array, outputting the URL + Link Text
for ($i = 0; $i < sizeof($linkarray[0]); $i++){
    echo (" " . $linkarray[2][$i] . " - <a href=" . $linkarray[1][$i] . "> Link " . $i . "</a><br>");



   // In case you want this as well.
   // Returns array of parsed request uri. Ex: array("path" => "/blog")
   $uri = parse_url($_SERVER['REQUEST_URI']); 


  //print_r ($host[1]);

 print_r (parseDomainName($linkarray[1][$i]));

  //print_r ($uri); 
  }

Everything works fine, except when it turns full length URLs into the domain and extension, it keeps the subdirectories. Example:

http://www.google.com/search.php

is turned into:

google.com/search.php

It should be shown as:

google.com

Help as to how to cut the

/blah....

out would be greatly appreciated,

Thanks,

Lee.
