今天我學到了
php發送給浏覽器設置編碼
header('content-type:text/html;charset=utf-8');
smarty模板引擎在類裡面會報N多錯
brophp裡的DB類,我修改了也無法單獨使用
thinkphp裡的DB類,我修改了也是不能單獨使用.
最後使用了 網上開源的 mysql類

使用方法
[php]
$db = new MySQL("127.0.0.1","root","","myly");
$db->table("data");
$list=$db->select()
$db = new MySQL("127.0.0.1","root","","myly");
$db->table("data");
$list=$db->select()
還使用到了 jquery做特效,移入移出效果
[javascript]
// JavaScript Document

$user=$("div .user");
$text=$("div .text");
$("div .content").each(function(index){
