php操作redis--增删改查

一.初始化redis对象//连接本地的 Redis 服务$redis = new Redis();$link = $redis->connect("127.0.0.1", 6379);if($link){ echo "Connection to server sucessfully <br/>";}else{ echo "Connection to server unsucessfully"; exit();}//查看服务是否运行//echo "Server is running: " . $redis->ping();  二.增加的模板<form action="reg.php" method="post"> 用户名: <input type="text" name="username" /><br/> 密码: <input type="password" name="password" /><br/> 年龄: <input type="text" name="age" /><br/> <input type="submit" value="注册" /> <input type="reset" value="重新填写" /></form>三.执行添加的php文件require("redis.php");$username = $_POST["username"];$password = MD5($_POST["password"]);$age = $_POST["age"];//自动增加函数incr()$uid = $redis->incr("userid");//添加用户$res = $redis->hmset("user:".$uid,array("uid"=>$uid,"username"=>$username,"password"=>$password,"age"=>$age));$redis->rpush("uid",$uid);if($res){ header("location:list.php");}四.列表展示--删除<?php require("redis.php"); //获取分页--首先知道总数,每页条数,当前页数,页总数 //用户总数 $count = $redis->lsize("uid"); //每页条数 $page_size = 3; //当前页数 $page_num = (!empty($_GET["page"]))?$_GET["page"]:1; //页总数 $page_count = ceil($count/$page_size); $ids = $redis->lrange("uid",($page_num-1)*$page_size,(($page_num-1)*$page_size+$page_size-1)); //取出当前的所有用户 /*for($i=1;$i<=($redis->get("userid"));$i++){ $data[] = $redis->hgetall("user:".$i); }*/ foreach($ids as $val){ $data[] = $redis->hgetall("user:".$val); } $data = array_filter($data);//过滤数组中的空元素?><table border=1> <tr> <th>uid</th> <th>username</th> <th>age</th> <th>操作</th> </tr><?php foreach($data as $val){ ?> <tr> <td><?php echo $val["uid"]; ?></td> <td><?php echo $val["username"]; ?></td> <td><?php echo $val["age"]; ?></td> <td><a href="del.php?id=<?php echo $val["uid"]?>">删除</a> <a href="edit.php?id=<?php echo $val["uid"]?>">编辑</a></td> </tr><?php } ?><tr> <td colspan="4"> <a href="?page=<?php echo (($page_num-1)<=1)?1:($page_num-1); ?>">上一页</a> <a href="?page=<?php echo (($page_num+1)>=$page_count)?$page_count:($page_num+1); ?>">下一页</a> <a href="?page=1">首页</a> <a href="?page=<?php echo $page_count; ?>">尾页</a> 当前<?php echo $page_num; ?>页 总共<?php echo $page_count; ?>页 总共<?php echo $count; ?>用户 </td></tr></table>五.删除文件require("redis.php");$uid = $_GET["id"];$res = $redis->del("user:".$uid);$redis->lrem("uid",$uid);if($res){ header("location:list.php");}六.修改文件<?php require("redis.php"); $uid = $_GET["id"]; $data = $redis->hgetall("user:".$uid);?><form action="doedit.php" method="post"><input type="hidden" value="<?php echo $data["uid"]; ?>" name="uid" /> 用户名: <input type="text" name="username" value="<?php echo $data["username"]; ?>" /><br/> 年龄: <input type="text" name="age" value="<?php echo $data["age"]; ?>" /><br/> <input type="submit" value="修改" /></form>七.执行修改require("redis.php");$uid = $_POST["uid"];$username = $_POST["username"];$age = $_POST["age"];$res = $redis->hmset("user:".$uid,array("username"=>$username,"age"=>$age));if($res){ header("location:list.php");}else{ header("location:edit.php");}
