PHP check if user are logged in

本文关键字：登录是否用户检查 PHP | 更新日期: 2023-09-27

嗨，伙计们，谁能帮帮我?我已经在下面创建了这个登录系统，我需要检查用户是否在访问管理区域"cpanel.php"之前登录。

authorize.php

<?php
try {
    $dbh = new PDO("mysql:host=localhost;dbname=vbl", "root", "");
        } catch (PDOException $e) {
            echo $e->getMessage();
            exit();
        }
$query = "SELECT * FROM `users` WHERE LOWER(`username`) = :username";
$stmt = $dbh->prepare($query);
$stmt->bindValue(':username', strtolower($_POST['username']));
$stmt->execute();
if ($stmt->rowCount() == 1) {
    $row = $stmt->fetch(PDO::FETCH_ASSOC);
    require('blowfish.class.php');
    $bcrypt = new Bcrypt(4);
    if ($bcrypt->verify($_POST['password'], $row['password'])) {
        header("location: cpanel.php");
        } else { 
            header("location: login.php");
    }
}
?>

顺便说一句，这是一种可以登录的方式吗?

按照以下步骤操作

Sept 1: Set session about your login user details

session_start();
$_SESSION['user_name']=$username;
$_SESSION['user_role']=$role;

步骤2:访问任意页面的会话

session_start();
if(isset($_SESSION['user_name']))
{
   //user logged in
   //do whatever you want
}
else
{
   //user did not logged in
}

步骤3:在注销页面销毁用户会话

session_start();
session_destroy();

一旦你在登录页面上创建了会话，你就可以在应用程序的任何页面上使用会话。
