PHP: Adding parameters to a url?
<p>If I have the url <code>mysite.com/test.php?id=1</code>. The <code>id</code> is set when the page loads and can be anything. There could also be others in there such as <code>?id=1&amp;sort=new</code>. Is there a way just to add another to the end without finding out what the others are first then building a new url? thanks. </p>
