How to add additional url parameters?

Question

I would like to know how I can include additional URL parameters to a given link? ie: 'news?pid=3'

<?php
print $path='news?pid=3';
?>

This returns page not found error as the '?' is getting printed as %3F.

Answer 1

If you are using l(), you would do something like this to create news?pid=3.

l('Link Text', 'news', array('query' => array('pid' => '3')));

If you have other query parameters, you can add them in like this:

l('Link Text', 'news', array('query' => array('pid' => '3', 'foo' => 'bar')));

and that would create news?pid=3&foo=bar.
