This code produces a list of OPTION tags from an array, array keys being option values and array items being option texts. It will also pre-select items from the second argument

<?php

                              Function array2select($arr,$sel = "") {

                                while ( list( $key, $val ) = each($arr)) {

                                    if($sel && ($key == $sel || is_array($sel) && in_array($key,$sel))) {

                                       $select_v=" selected";

                                    } else { 

                                       $select_v=""; 

                                        }

                                    echo "<option value="$key" $select_v>$val</option>n";

                                }

                              }
?>
