how do i grab all parameters in the url and print it out?
<p>if i have a link like this</p>

<p><a href="http://www.website.com/index.php?a=1&amp;b=2&amp;c=3&amp;d=4" rel="nofollow">http://www.website.com/index.php?a=1&amp;b=2&amp;c=3&amp;d=4</a></p>

<p>how can i print out all the parameters and its values without doing <code>print $_POST['a'];</code></p>

<p>thanks</p>
