使用示例：

    
    
    


layout=false;                   //不使用表格布局，大家可以把这句注释掉看结果有何不同
$name=$form->form_text("userid","userid","用户名","userid");
$passwd=$form->form_passwd("passwd","passwd","密码","passwd");
$submit=$form->form_button("","submit","submit","登录");
$form_item=array($name,$passwd,$submit);
$form->CreateForm($form_item);
?>
