Som 1 funktion

Hej hej,
hvordan "gemmer" jeg nedenstående som en funktion, så jeg kan kalde den recursive kode der afvikles?
---------------------------

<select name="news_archive_id" style="width: 206px" class="input">
<?php

$con = mysql_connect( ****, ****, **** );
    mysql_select_db( ****, $con );
   
    $results = array();
   
        function news_archives_list( $parent, $indent = 0 )
        {
            global $results;
            $sql = "SELECT * FROM tbl_news_archive WHERE news_archive_parent_id = $parent";
            //echo $sql."<br />";
            $res = mysql_query( $sql );
            if ( mysql_num_rows( $res ) > 0 )
            {
                while ( $row = mysql_fetch_assoc( $res ) ) {
                    $results[] = array("news_archive_name" => $row['news_archive_name'], "news_archive_id" => $row['news_archive_id'], "news_archive_parent_id" => $row['news_archive_parent_id'], "indent" => $indent);
                    news_archives_list( $row['news_archive_id'], $indent + 1 );
                }
            mysql_free_result( $res );
            }
        }
       
        news_archives_list( 0 );
       
        $n = count( $results );
       
        foreach ( $results as $row )
        {
        $line.= "";
        $indent = str_repeat( "'-", $row['indent'] );
            if ($row['indent'] == 0) {
                $line.= "<option value=\"".$row[news_archive_id]."\">".$row[news_archive_name]."</option>\n";
            } else {
                $line.= "<option value=\"".$row[news_archive_id]."\">".$indent." ".$row[news_archive_name]."</option>\n";
            }
        }
        echo $line;

?>
</select>
