What are the advantages and disadvantages of using a CMS for building a community website compared to coding everything from scratch in PHP?

Using a CMS for building a community website can offer advantages such as faster development time, built-in features like user management and content editing, and a lower learning curve for non-technical users. However, it may limit customization options, have performance limitations, and require regular updates for security reasons.

// Example PHP code snippet for building a basic user registration form from scratch

<form action="register.php" method="post">
    <input type="text" name="username" placeholder="Username" required>
    <input type="email" name="email" placeholder="Email" required>
    <input type="password" name="password" placeholder="Password" required>
    <button type="submit">Register</button>
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data and save user information to database
    $username = $_POST['username'];
    $email = $_POST['email'];
    $password = password_hash($_POST['password'], PASSWORD_DEFAULT);

    // Insert user data into database
    // Example SQL query: INSERT INTO users (username, email, password) VALUES ('$username', '$email', '$password')
}
?>
