1、登錄頁面php

封裝BDDAcss

<?php
class DBDA{
    public $host="localhost"; //服務器地址
    public $uid="root"; //用戶名
    public $pwd="123"; //密碼
    public $dbname="shopping"; //數據庫名稱
     
    /*
        執行一條SQL語句的方法
        @param sql 要執行的SQL語句
        @param type SQL語句的類型，0表明查詢 1表明增刪改
        @return 若是是查詢語句返回二維數組，若是是增刪改返回true或false
    */
    public function query($sql,$type=0){
        $db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname);
        $result = $db->query($sql);
        if($type){
            return $result;
        }else{
            return $result->fetch_all();
        }
    }
    public function strquery($sql,$type=0){
        $db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname);
        $result = $db->query($sql);
        if($type){
            return $result;
            }else{
                $arr = $result->fetch_all();
                $str = "";
                foreach($arr as $v){
                    $str .= implode("^",$v)."|";
                    }
                $str = substr($str,0,strlen($str)-1);
                return $str;
                }
        }
    //返回json數據的方法
    public function jsonquery($sql,$type=0){
        $db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname);
        $result = $db->query($sql);
        if($type){
            return $result;
        }else{
            $arr = $result->fetch_all(MYSQLI_ASSOC);//關聯數組
            return json_encode($arr);//轉換json
            //json_decode()分解json
        }
    }
}

css樣式表html

 *{
    margin:0px auto;
    padding:0px;
    }
#login{
    background-color:#0CF;
    width:30%;
    height:200px;
    margin-top:50px;
    border:5px double #060;
    }
#dl{
    color:#00F;
    background-color:#9FF;
    height:30px;
    text-indent:10px;
    vertical-align:bottom;
    line-height:30px;
    }
#pwd{
    background-color:#CFF;
    height:70px;
    }
#sb{
    background-color:#060;
    width:200px;
    height:30px;
    color:#CFF;
    margin-top:3px;
    }

　佈局樣式sql

<body>
    <form method="post" action="dengluchuli.php">
    <div id="login">
        <div align="left" id="dl">登陸頁面</div><br />
        <div id="yhm" align="center">用戶名：
        <input type="text" placeholder="請輸入用戶名" name="uid"/></div><br />
        <div id="pwd" align="center">密   碼：
        <input type="password" placeholder="請輸入密碼" name="pwd"/></div>
        <div align="center"><input type="submit" value="登陸" id="sb"/></div>
    </div>
    </form>
</body>

2、登陸處理數據庫

<?php
session_start();
require_once "../DBDA.class.php";
$db = new DBDA();
 
$uid = $_POST["uid"];
$pwd = $_POST["pwd"];
 
$sql = "select password from login where username='{$uid}'";
$mm = $db->strquery($sql);
if(!empty($pwd) && $pwd==$mm){
    $_SESSION["uid"] = $uid;
    header("location:main.php");
}else{
    header("location:denglu.php");
}

 3、主頁的css樣式json

　*{
    margin:0px auto;
    padding:0px;
    }
　　　　　　#shang{
    background-color:#0FF;
    width:100%;
    height:60px;
    vertical-align:bottom;
    line-height:90px;
    text-indent:10px;
    }
　　#zuo{
    float:left;
    background-color:#999;
    width:30%;
    height:500px;
    }
.caidan{
    width:80%;
    height:60px;
    background-color:#69F;
    margin-top:20px;
    text-align:center;
    vertical-align:middle;
    line-height:60px;
    font-weight:bold;
    }
　　#yous{
    height:40px;
    width:100%;
    background-color:#FFF;
    vertical-align:bottom;
    line-height:60px;
    text-indent:10px;
    color:#009;
    font-size:20px;
    }  
　　#you{
    background-color:#06F;
    width:70%;
    height:500px;
    float:left;
    }
　　table{
    color:#CF0;
    text-align:center;
    }
