目的：通过留言板(todolist)与互粉功能，掌握php操作redis的方法
相关数据操作命令
1，keys * 查看数据库所有的key
2，type + key: 如 type uid 查看数据key的类型
3，批量删除key, 如redis-cli keys "auth:*" | xargs redis-cli del 这行命令在linux终端执行， 删除 auth: 开头的所有key
4。。。。其他基本常用命令， 参照百度或者redis手册
0，连接redis
1 <?php2 3 $redis = new Redis();4 $redis->connect( "127.0.0.1", 6379 );5 $redis->auth( "ghostwu" );6 7 ?>
1、注册功能( reg.php )
1 <!doctype html> 2 <html> 3 ????<head> 4 ????????<meta charset="utf-8" /> 5 ????????<title>用户注册页面</title> 6 ????</head> 7 ????<body> 8 ????????<h3>用户注册</h3> 9 ????????<form action="do_reg.php" method="post">10 ????????????<p>11 ????????????????用户名: <input type="text" name="user" />12 ????????????</p>13 ????????????<p>14 ????????????????密码：<input type="password" name="pwd" />15 ????????????</p>16 ????????????<p>17 ????????????????年龄: <input type="text" name="age" />18 ????????????</p>19 ????????????<p>20 ????????????????<input type="submit" value="注册" />21 ????????????????<input type="reset" value="重置" />22 ????????????</p>23 ????????</form>24 ????</body>25 </html>
2、处理注册( do_reg.php )
1 <?php 2 require "./redis_connect.php"; 3 ?4 $user = $_POST[‘user‘]; 5 $pwd = md5( $_POST[‘pwd‘] ); 6 $age = $_POST[‘age‘]; 7 ?8 $uid = $redis->get( "username:" . $user ); 9 if( empty( $uid ) ) {10 ????$uid = $redis->incr( "userid" );11 ????$redis->hMset( "user:" . $uid, array( "uid" => $uid, "user" => $user, "pwd" => $pwd, "age" => $age ) );12 ????$redis->rpush( "uid", $uid );13 ????$redis->set( "username:" . $user, $uid );14 ????header( "Location:./list.php" );15 ????exit();16 }else {17 ????die( "user already exists " );18 }19 20 ?>3，登录(login.php)
1 <!doctype html> 2 <html> 3 ????<head> 4 ????????<meta charset="utf-8" /> 5 ????????<title>用户登录页面</title> 6 ????</head> 7 ????<body> 8 ????????<?php 9 ????????????require "./redis_connect.php";10 ????????????if( isset( $_POST[‘login‘] ) || $_POST[‘login‘] == ‘登录‘ ) {11 ????????????????$user = $_POST[‘user‘];12 ????????????????$pwd = $_POST[‘pwd‘];13 ????????????????$uid = $redis->get( "username:" . $user );14 ????????????????if( !empty( $uid ) ) {15 ????????????????????$db_pwd = $redis->hget( "user:" . $uid, "pwd" );16 ????????????????????if( md5( $pwd ) == $db_pwd ) {17 ????????????????????????$auth = md5( time() . $user . rand() );18 ????????????????????????$redis->set( "auth:" . $auth, $uid );19 ????????????????????????setcookie( "auth", $auth, time() + 86400 );20 ????????????????????????header( "Location:./list.php" );21 ????????????????????}else {22 ????????????????????????echo "<script>alert(‘用户密码错误‘);</script>";23 ????????????????????}24 ????????????????}else {25 ????????????????????echo "<script>alert(‘该用户不存在‘);</script>";26 ????????????????}27 ????????????}28 ?????????>29 ????????<h3>用户登录</h3>30 ????????<form action="" method="post">31 ????????????<p>32 ????????????????用户名: <input type="text" name="user" />33 ????????????</p>34 ????????????<p>35 ????????????????密码：<input type="password" name="pwd" />36 ????????????</p>37 ????????????<p>38 ????????????????<input type="submit" value="登录" name="login" />39 ????????????</p>40 ????????</form>41 ????</body>42 </html>4，列表页( list.php )
