自己写的一个PHP面向对象方式的页面生成库（同时支持Web和Wap）
自己写的一个PHP面向对象方式的页面生成库，还有很多未完善的，抛砖引玉而已，边用边完善吧。
下面是类库的代码：

下面是使用的例子，完成一个简单的百度搜索：

include_once('uis.php');
$pag = UIPage(true); // true表示输出的是web页面,如果是false则输出wap页面
$pag->title->add('测试页面');
$div = UIDiv();
$pag->body->add($div);
uif_align($div); //居中对齐
$div->add('HelloWorld');
$div->add(UIBr());
// 下面创建一个表达
$form = UIForm('GET','http://www.baidu.com/s');
$form->add(UIInput('wd')); // 文本框
$form->add(UIInput('submit', 'submit', '搜索')); // 提交按钮
$div->add($form); // 添加到div中
// 最后输出
header("Content-Type: text/html; charset=UTF-8");
echo $pag->toPage();
