互刷PHP源码通常是指一个用于实现网站或应用程序之间互相推广的系统,以下是一个简单的互刷PHP源码示例,包括用户注册、登录、发布任务和完成任务等功能。
1、数据库连接文件(db.php):
<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // 创建连接 $conn = new mysqli($servername, $username, $password, $dbname); // 检测连接 if ($conn>connect_error) { die("连接失败: " . $conn>connect_error); } ?>
2、用户注册功能(register.php):
<?php include 'db.php'; if (isset($_POST['submit'])) { $username = $_POST['username']; $password = $_POST['password']; $email = $_POST['email']; $sql = "INSERT INTO users (username, password, email) VALUES ('$username', '$password', '$email')"; if ($conn>query($sql) === TRUE) { echo "注册成功"; } else { echo "Error: " . $sql . "<br>" . $conn>error; } } ?> <form method="post" action=""> 用户名: <input type="text" name="username"><br> 密码: <input type="password" name="password"><br> 邮箱: <input type="email" name="email"><br> <input type="submit" name="submit" value="注册"> </form>
3、用户登录功能(login.php):
<?php session_start(); include 'db.php'; if (isset($_POST['submit'])) { $username = $_POST['username']; $password = $_POST['password']; $sql = "SELECT * FROM users WHERE username='$username' AND password='$password'"; $result = $conn>query($sql); if ($result>num_rows > 0) { $_SESSION['username'] = $username; header("Location: tasks.php"); } else { echo "用户名或密码错误"; } } ?> <form method="post" action=""> 用户名: <input type="text" name="username"><br> 密码: <input type="password" name="password"><br> <input type="submit" name="submit" value="登录"> </form>
4、发布任务功能(publish_task.php):
<?php session_start(); include 'db.php'; if (!isset($_SESSION['username'])) { header("Location: login.php"); } if (isset($_POST['submit'])) { $task_title = $_POST['task_title']; $task_description = $_POST['task_description']; $user_id = $_SESSION['user_id']; $sql = "INSERT INTO tasks (title, description, user_id) VALUES ('$task_title', '$task_description', '$user_id')"; if ($conn>query($sql) === TRUE) { echo "任务发布成功"; } else { echo "Error: " . $sql . "<br>" . $conn>error; } } ?> <form method="post" action=""> 任务标题: <input type="text" name="task_title"><br> 任务描述: <textarea name="task_description"></textarea><br> <input type="submit" name="submit" value="发布任务"> </form>
5、完成任务功能(complete_task.php):
<?php session_start(); include 'db.php'; if (!isset($_SESSION['username'])) { header("Location: login.php"); } if (isset($_POST['submit'])) { $task_id = $_POST['task_id']; $user_id = $_SESSION['user_id']; $sql = "UPDATE tasks SET completed=1 WHERE id='$task_id' AND user_id='$user_id'"; if ($conn>query($sql) === TRUE) { echo "任务完成成功"; } else { echo "Error: " . $sql . "<br>" . $conn>error; } } ?> <form method="post" action=""> 任务ID: <input type="text" name="task_id"><br> <input type="submit" name="submit" value="完成任务"> </form>
注意:以上代码仅作为示例,实际应用中需要考虑安全性问题,如防止SQL注入、使用预处理语句等,还需要对用户输入进行验证和过滤,确保数据的正确性和安全性。
