What are some potential alternatives to using MySQL as a backend for a small CMS in PHP?

One potential alternative to using MySQL as a backend for a small CMS in PHP is to use SQLite. SQLite is a lightweight, serverless database engine that can be easily integrated into PHP applications. It requires minimal setup and configuration, making it a good choice for small projects where scalability is not a major concern.

// Example of using SQLite as a backend for a small CMS in PHP

// Create a new SQLite database connection
$pdo = new PDO('sqlite:database.db');

// Create a table for storing CMS data
$pdo->exec("CREATE TABLE IF NOT EXISTS pages (
    id INTEGER PRIMARY KEY,
    title TEXT,
    content TEXT
)");

// Insert a new page into the database
$stmt = $pdo->prepare("INSERT INTO pages (title, content) VALUES (:title, :content)");
$stmt->bindParam(':title', $title);
$stmt->bindParam(':content', $content);

$title = 'About Us';
$content = 'This is the about us page content.';
$stmt->execute();

// Retrieve all pages from the database
$pages = $pdo->query("SELECT * FROM pages")->fetchAll(PDO::FETCH_ASSOC);

// Output the pages
foreach ($pages as $page) {
    echo '<h2>' . $page['title'] . '</h2>';
    echo '<p>' . $page['content'] . '</p>';
}
