PHP HTML class / printing SELECT dropdown box

/*
Here's a very handy class function for printing HTML SELECT. I normally use it with dynamic
arrays i.e. result set from an SQL query
*/

class html {

	function print_select($select_name, $select_array, $selected_value="", $js="", $multiple="")
{
		//
		// print a select box
		// parameters: 
		// 1. name of the select box
		// 2. array with keys and values
		// 3. selected value(s)
		// 4. javascript
		// 5. multiple
		//

		print ( "\n<SELECT NAME=\"" . $select_name . "\" " .
						$multiple . " " . $js . ">\n" );

		while (list ($key, $val) = each ($select_array)) {
			if ($multiple == "MULTIPLE") {
				if (is_array($selected_value)) {
					if (in_array($key, $selected_value)) {
						print ( "\t<OPTION VALUE=\"" .
						$key . "\" SELECTED>" . $val ."</OPTION>\n" );
					} else {
						print ( "\t<OPTION VALUE=\"" .
						$key . "\">" . $val ."</OPTION>\n" );
					}
				} else {
					print ( "\t<OPTION VALUE=\"" .
					$key . "\">" . $val ."</OPTION>\n" );
				}
			} else {
				if ($key == $selected_value) {
					print ( "\t<OPTION VALUE=\"" .
					$key . "\" SELECTED>" . $val ."</OPTION>\n" );
				} else {
					print ( "\t<OPTION VALUE=\"" .
					$key . "\">" . $val ."</OPTION>\n" );
				}
			}
		}

		print ( "</SELECT>\n" );

	}

	//
	// Put some other functions here ...
	//

}

"OnChange=\"this.form.submit();\"");
