                                <option>Selecione...</option>

                                

                                <?php                                   

                                    $select = 'SELECT id, nome FROM clientes';                                    

 

                                    while($cli = mysql_fetch_array($select)) { ?>

                                        <option value="<?php echo $cli['id'] ?>"><?php echo $cli['nome'] ?></option>

                                        <?php }
