php模拟OICQ的用户登陆部分

1 登陆表单，请看我的主页的文本源代码吧！这里我就不多写了！！

2 login.php 用户登陆，注册 session 等工作！

<?

session_start();

session_register("name");

session_register("password");

session_register("photo");

session_register("loginsign");

session_register("level");

session_register("place");

$name=$password="";

$chatsign=$loginsign=0;

$menusave=" ";

$mysqlusername = "php2000";

$mysqlpassword = "";

$hander = mysql_connect("localhost",$mysqlusername,$mysqlpassword);

mysql_select_db("php2000");

$loginsign =0;

if(($loginname != "") && ($loginpass != ""))

{

$name = $loginname;

$password = $loginpass;

$userloginsign=1;

}

if( ($name == "") || ($password == ""))

{

$loginsign =0;

}

else

{

$msg = mysql_fetch_array($result=mysql_query("select password,level,status from userinfo where name='$name'"));

if( ( mysql_num_rows($result) == 1) && ($msg['password'] == $password) )

{

$loginsign = 1;

$level = $msg['level'];

$photo = $messageuser['face'];

$timecurrent = date("U");

if( ($lastenterdate = $messageuser['enterdate']) == 0) $lastenterdate = $timecurrent;

mysql_query("update userinfo set

ip='$ip',ipfrom='$ipfrom',onlinestatus=1,enterdate=$timecurrent,entertimes=entertimes+1,lastenterdate=$lastenterdate,currentdate=$timecurrent,chatroom='

where name = '$name'");

}

}

header("location:index.php");
