如何利用PHP技术打造高效的家教网站？

我可以帮助你创建一个PHP家教网站，以下是一个详细的指南，包括代码示例和解释。

项目结构

我们需要定义项目的文件结构：

teaching-platform/
│
├── index.php
├── about.php
├── contact.php
├── login.php
├── register.php
├── dashboard.php
├── logout.php
├── styles.css
└── db.php

数据库连接 (`db.php`)

在db.php 文件中，我们将设置与MySQL数据库的连接。

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "teaching_platform";
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检查连接
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
?>

首页 (`index.php`)

这是网站的主页，展示一些基本信息和登录链接。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Teaching Platform</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <header>
        <h1>Welcome to the Teaching Platform</h1>
        <nav>
            <ul>
                <li><a href="about.php">About</a></li>
                <li><a href="contact.php">Contact</a></li>
                <li><a href="login.php">Login</a></li>
                <li><a href="register.php">Register</a></li>
            </ul>
        </nav>
    </header>
    <main>
        <h2>Find Your Perfect Tutor</h2>
        <p>Join our platform and find the best tutor for your needs.</p>
    </main>
    <footer>
        <p>&copy; 2023 Teaching Platform</p>
    </footer>
</body>
</html>

4. 关于页面 (about.php)

简单的关于页面。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>About Teaching Platform</title>
    <link rel="stylesheet" href="styles.css">

<body>
    <header>
        <h1>About Us</h1>
        <nav>
            <ul>
                <li><a href="index.php">Home</a></li>
                <li><a href="contact.php">Contact</a></li>
                <li><a href="login.php">Login</a></li>
                <li><a href="register.php">Register</a></li>
            </ul>
        </nav>
    </header>
    <main>
        <h2>Our Mission</h2>
        <p>We aim to provide the best education resources to help students achieve their goals.</p>
    </main>

                <li><a href="register.php">Register</a></li>
            </ul>
        </nav>
    </header>
    <main>
        <h2>Get in Touch</h2>
        <form action="contact_submit.php" method="post">
            <label for="name">Name:</label><br>
            <input type="text" id="name" name="name"><br><br>
            <label for="email">Email:</label><br>
            <input type="email" id="email" name="email"><br><br>
            <label for="message">Message:</label><br>
            <textarea id="message" name="message"></textarea><br><br>
            <input type="submit" value="Submit">

    </main>
    <footer>

    <link rel="stylesheet" href="styles.css">

    <header>
        <h1>Register</h1>
        <nav>
            <ul>
                <li><a href="index.php">Home</a></li>

        <p>&copy; 2023 Teaching Platform</p>
    </footer>
</body>
</html>

7. 登录页面 (login.php)

用户登录页面。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Login Teaching Platform</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <header>
        <h1>Login</h1>
        <nav>
            <ul>
                <li><a href="index.php">Home</a></li>

            </ul>
        </nav>
    </header>
    <main>
        <h2>Login to Your Account</h2>
        <form action="login_submit.php" method="post">
            <label for="username">Username:</label><br>
            <input type="text" id="username" name="username"><br><br>
            <label for="password">Password:</label><br>
            <input type="password" id="password" name="password"><br><br>

    <footer>
        <p>&copy; 2023 Teaching Platform</p>
    </footer>
</body>
</html>

8. 仪表盘页面 (dashboard.php)

用户登录后的仪表盘页面，这里假设用户已经登录并会话已启动。

<?php session_start(); ?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Dashboard Teaching Platform</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <header>
        <h1>Dashboard</h1>
        <nav>
            <ul>
                <li><a href="index.php">Home</a></li>
                <li><a href="about.php">About</a></li>
                <li><a href="contact.php">Contact</a></li>
                <li><a href="logout.php">Logout</a></li>
            </ul>
        </nav>
    </header>
    <main>
        <h2>Welcome, <?php echo $_SESSION['username']; ?>!</h2>
        <!-Add more content here -->
    </main>
    <footer>
        <p>&copy; 2023 Teaching Platform</p>
    </footer>
</body>
</html>

9. 注销页面 (logout.php)

处理用户注销。

<?php session_start(); session_destroy(); header('Location: index.php'); ?>

10. 样式表 (styles.css)

简单的CSS样式表。

body { font-family: Arial, sans-serif; }
header { background-color: #f8f9fa; padding: 1em; text-align: center; }
nav ul { list-style-type: none; padding: 0; }
nav li { display: inline; margin: 0 1em; }
main { padding: 1em; }
footer { background-color: #f8f9fa; text-align: center; padding: 1em; position: fixed; bottom: 0; width: 100%; }

11. 提交表单处理脚本 (contact_submit.php,register_submit.php,login_submit.php)

这些脚本将处理表单提交并将数据存储到数据库中，以下是register_submit.php 的示例：

<?php include 'db.php'; ?>
<?php if ($_SERVER["REQUEST_METHOD"] == "POST"): ?>
    <?php 
        $username = $_POST['username']; 
        $password = password_hash($_POST['password'], PASSWORD_DEFAULT); // hash the password before storing it in the database 
        $email = $_POST['email']; 
        $sql = "INSERT INTO users (username, password, email) VALUES ('$username', '$password', '$email')"; 
        if ($conn->query($sql) === TRUE) { 
            echo "New record created successfully"; 
        } else { 
            echo "Error: " . $sql . "<br>" . $conn->error; 
        } 
    ?> 
<?php endif; ?>

请确保在数据库中有一个名为users 的表，并且包含username,password,email 字段，你可以使用以下SQL语句来创建这个表：

CREATE TABLE users (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(30) NOT NULL,
    password VARCHAR(255) NOT NULL,
    email VARCHAR(50),
    reg_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);
