单击超链接php时，URL会被附加

Question

我正在用PHP写一个小网页。单击超链接时，超链接将被附加

function get_url($ff) {
  $q = isset($_REQUEST['query']) ? $_REQUEST['query'] : NULL;
  return "http" . (($_SERVER['SERVER_PORT']==443) ? "s://" : "://") . $_SERVER['HTTP_HOST'] .'?query=' .$q. '&bw' . '=' . $ff ;
} 

 <li><a href="<?php print get_url('exampl');?>">example</a></li>

输出网址

http://example.com/test/?query=search&bw=test.

点击下次我点击

http://example.com/test/?query=search&bw=test?query=search&bw=test.

Answer 1

更改此

return "http" . (($_SERVER['SERVER_PORT']==443) ? "s://" : "://") . $_SERVER['HTTP_HOST'] .'?query=' .$q. '&bw' . '=' . $ff ;

到

return "http" . (($_SERVER['SERVER_PORT']==443) ? "s://" : "://") . $_SERVER['SERVER_NAME'] .'?query=' .$q. '&bw' . '=' . $ff ;
