    }
    function CreateForm($form_item=array()){

        foreach ($form_item as $item){
            echo $item;
        }
        echo $this->form_end();
    }
}
?>

使用示例：

    
    
    


<?php
require_once("form.php");
$form=new form($_SERVER['PHP_SELF']);   //提交到本页
$form->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);
?>
