mysql_query($sql);記得所有數(shù)據(jù)前面addslashes一下防止mysql注入
首先得到提交的數(shù)據(jù)
鏈接數(shù)據(jù)庫,查詢數(shù)據(jù)庫,查詢username 和pwd
提交的username 和 pwd? 跟數(shù)據(jù)庫查詢的username 和pwd做對(duì)比,
都相等那就是登陸成功
?php
mysql_connect('localhost','root','123');
mysql_select_db('lx');
mysql_query("SET?CHARACTER?SET?utf8");
mysql_query("SET?NAMES?utf8");
//數(shù)據(jù)庫lx?表user??字段id?username??pwd
//用md5加密,可以自己試試????
if(isset($_POST['user'])$_POST['tijiao']?==?'success'){
$query?=?mysql_query("select?pwd?from?user?where?username?=?'".$_POST['user']."'");
$num?=?mysql_num_rows($query);
if($num??0?){
while($info?=?mysql_fetch_array($query)){
if($info['pwd']?==?md5($_POST['pwd'])){
echo?'登陸成功';
}else{
echo?'登陸失敗';????
}
}

是不懂做要用到數(shù)據(jù)庫的網(wǎng)站嗎?那樣的話。
網(wǎng)上有很多配置PHP數(shù)據(jù)庫的教程的。
可以搜一下。

數(shù)據(jù)庫你就自己建,望采納~
登錄就是查詢數(shù)據(jù)庫表中是否有這一條用戶信息,
注冊(cè)就是插入一條新的用戶信息
