后台地址为http://域名/admin账号密码都是admin
conn.php打开如下

<?
mysql_connect("localhost","lfggw","lfggw");
mysql_select_db("niuchao513");
mysql_query("set names 'gbk'");
date_default_timezone_set('PRC');
function Q($str){
return mysql_query($str);
}
function R($str){
return mysql_fetch_array(mysql_query($str));
}
function F($result){
return mysql_fetch_array($result);
}
function mstr($str, $start, $len) {
$tmpstr = "";
$strlen = $start + $len;
for($i = 0; $i < $strlen; $i++) {
if(ord(substr($str, $i, 1)) > 0xa0) {
$tmpstr .= substr($str, $i, 2);
$i++;
} else
$tmpstr .= substr($str, $i, 1);
}
return $tmpstr;
}
function showi($str,$url){
if($url=="-1"){
echo "<script>alert('$str');history.go(-1);</script>";
}
else{
echo "<script>alert('$str');location.href='$url';</script>";
}
exit;
}
function goi($url){
if($url=="-1"){
echo "<script>history.go(-1);</script>";
}
else{
echo "<script>location.href='$url';</script>";
}
exit;
}
function GetIP()
{
if(!empty($_SERVER["HTTP_CLIENT_IP"]))
{
$cip = $_SERVER["HTTP_CLIENT_IP"];
}
else if(!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
{
$cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
}
else if(!empty($_SERVER["REMOTE_ADDR"]))
{
$cip = $_SERVER["REMOTE_ADDR"];
}
else
{
$cip = '';
}
preg_match("/[\d\.]{7,15}/", $cip, $cips);
$cip = isset($cips[0]) ? $cips[0] : 'unknown';
unset($cips);
return $cip;
}
function GetTitle($id){
$r=R("select t from fafa where id='$id'");
return $r['t'];
}
$userid=getcookieid();
function getcookieid(){
$uid=@$_COOKIE['fafa_userid'];
if($uid==""){
$uid=0;
}
return $uid;
}

Answer 1

建议你使用mysqli，面向对象的，比起mysql来说方便多了，数据连接mysqli（‘h’，‘u’，‘p','d')，然后返回给一个对象就行了

Answer 2

mysql_connect("localhost","用户名","密码");
mysql_select_db("数据库名");
