Nice Filter Terms in PHP

nice-filter-terms.php

<?
if ($url_parts[1]!='') 
{
	$args = array();
	for($i=0; $i<count($url_parts);$i++) {
		switch($url_parts[$i]) {
			case 'page':
			{
				$args['page']=$url_parts[$i+1];
				break
			}
			case 'from':
			{
				$args['from']=$url_parts[$i+1];
				break;
			}
			case 'over':
			{
				$args['over']=$url_parts[$i+1];
				break
			}
			case 'under':
			{
				$args['under']=$url_parts[$i+1];
				break;
			}
			case 'near':
			{
				$args['near']=$url_parts[$i+1];
				break;
			}
		}
	}
	search($args);
}
?>

Could probably make this cleaner with an array of terms, and assign with $args[$term].
