网站开发，必先利其器。mysql分页很方便，但是程序如何翻页呢？可能大家都有自己的解决方案，我也把我的方法共享出来，大家一起讨论吧。该myPager类继承自PEAR/Pager类，自动保留提交过来的GET和POST参数，并以url参数传递：

<?php
// --------------------------------------------------------------------------
// 文件名 : myPager.class.php
// 描述 : 继承自Pear/Pager/Pager.php,为其加上页码跳转
// 菜单，注意若要自动保留查询参数，则表单数据需要用
// GET方法提交
// 需求 : PHP4 ([url]http://www.php.net[/url])
