php网站登录注册源码
//login.php 负责处理用户登录与退出动作
if(!isset($_POST['submit'])){
exit('非法访问!');
}
$username = htmlspecialchars($_POST['username']);
$password = MD5($_POST['password']);
//包含数据库连接文件
include('conn.php');
//检测用户名及密码是否正确
$check_query = mysql_query("select uid from user where username='$username' and password='$password' limit 1");
if($result = mysql_fetch_array($check_query)){
//登录成功
$_SESSION['username'] = $username;
$_SESSION['userid'] = $result['uid'];
echo $username,' 欢迎你！进入 a href="my.php"用户中心/a
';
echo '点击此处 a href="login.php?action=logout"注销/a 登录！
';
exit;
} else {
exit('登录失败！点击此处 a href="javascript:history.back(-1);"返回/a 重试');
}
注：上述源码是在TP中的登录验证方法，供参考！！
求一用php写的注册和登录页面代码
reg.php文件
?php
header("Content-type:text/html;charset=utf-8");
if($_POST){
$dsn = 'mysql:dbname=1104javab;host=127.0.0.1';
$user = 'root';
$password = '';
try{
$pdo = new pdo($dsn,$user,$password,array(PDO::MYSQL_ATTR_INIT_COMMAND = 'SET NAMES \'UTF8\'')
);
}catch(Exception $e){
echo '错误'.$e-getmessage();
}
$name = $_POST['name'];
$pwd = md5($_POST['pwd']);
$sql = "insert into 表 (username,password) values ('$name','$pwd')";
$exec = $pdo-query($sql);
if($exec){
echo "scriptalert('成功');location.href='reg.html'/script";
}else{
echo "scriptalert('失败');location.href='reg.html'/script";
}
}
?
reg.html文件
form action='reg.php' method='post'
用户名:input type='text' name='name'
密码:input type='password' name='pwd'
input type='submit' value='submit'
/form
login.html文件
form action='reg.php' method='post'
用户名:input type='text' name='name'
密码:input type='password' name='pwd'
input type='submit' value='submit'
/form
login.php文件
header("Content-type:text/html;charset=utf-8");
if($_POST){
$dsn = 'mysql:dbname=1104javab;host=127.0.0.1';
$user = 'root';
$password = '';
try{
$pdo = new pdo($dsn,$user,$password,array(PDO::MYSQL_ATTR_INIT_COMMAND = 'SET NAMES \'UTF8\'')
);
}catch(Exception $e){
echo '错误'.$e-getmessage();
}
$name = $_POST['name'];
$pwd = $_POST['pwd'];
$sql = "select user_id from 表名 where username='$name' and password='$pwd'";
$stmt = $pdo-query($sql);
$info = $stmt-fetch(PDO::FETCH_ASSOC);
if($info){
echo "登录成功";
}else{
echo "登录失败";
}
}
大概这样

mysql_close($con)

我自己写的 很简单，100%适合新人。加密了密码，利用的是MD5
input type="submit" name="submit" value="注册"/form/body/html?php include ('conn.php
