介面：

<html><head><title>Logintitle>head><body><formname="fangbei"method="post"action="check_session_login.php"><divstyle="width:353"><dl><dt>dt><dd><divalign="left">       Username:       <inputtype="text"name="username" />div>dd><dd><divalign="left">       Password :        <inputtype="password"name="pwd" />div>dd><dd><palign="center"><inputtype="submit"name="Submit"value="Submit" /><inputtype="reset"name="Reset"value="Reset" />p>dd>dl>div>form>body>html>

資料庫準備：

username	pwd	userflag
perry	123	1

登入驗證：

header("Content-Type: text/html; charset=utf-8");$servername="localhost";$username = "root";$password = "";$dbname = "paul";$conn = new mysqli($servername, $username, $password, $dbname);if ($conn->connect_error) {    die("Connection failed: " . $conn->connect_error);}$conn->query("SET NAMES utf8");//擷取輸入的資訊$username = $_POST['username'];$pwd = $_POST['pwd'];//擷取session的值$sql = "select username,userflag from test_login where username = '$username' and pwd = '$pwd'";$result = $conn->query($sql);//判斷使用者以及密碼if ($result->num_rows > 0) {    session_start();    //判斷許可權$row = $result->fetch_assoc();    if($row['userflag'] == 1or$row['userflag'] == 0){        $_SESSION['username'] = $row['username'];        $_SESSION['userflag'] = $row['userflag'];        echo"歡迎訪問";    }    else{        echo"迷之使用者";    }}else{    echo"使用者名稱或密碼不正確";}

歡迎介面：

header("Content-Type: text/html; charset=utf-8");session_start();if(isset($_SESSION['username'])){    if($_SESSION['userflag'] == 1)        echo"歡迎管理員".$_SESSION['username']."登入";    if($_SESSION['userflag'] == 0)        echo"歡迎使用者".$_SESSION['username']."登入";}else{    echo"登入已到期";}unset($_SESSION['username']);unset($_SESSION['pwd']);unset($_SESSION['userflag']);echo"
會話結束";

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i <= lines; i++) { $numbering.append($('

').text(i)); }; $numbering.fadeIn(1700); }); });
