  $username=$_POST['username'];

  if (preg_match('~(?:[a-z0-9+.-]+://)?(?:\w+\.)+\w{2,6}\S*~i', $username))

  {

  die('Access Denied Avoid Link');

Pls do help me.............

Use something like..

if instr(url, sample) > 0 then
'do something
end if

Where URL is link and SAMPLE is the domain part (myopenid).
