What are the advantages of using SQLite over traditional file storage methods in PHP?

Using SQLite over traditional file storage methods in PHP offers several advantages, such as better performance due to its efficient storage and retrieval mechanisms, built-in support for SQL queries for data manipulation, and ACID compliance for data integrity. Additionally, SQLite databases are self-contained files that can be easily transferred or backed up, making them a convenient choice for small to medium-sized applications.

// Connect to SQLite database
$db = new SQLite3('database.db');

// Create a table
$query = "CREATE TABLE IF NOT EXISTS users (
    id INTEGER PRIMARY KEY,
    username TEXT NOT NULL,
    email TEXT NOT NULL
)";
$db->exec($query);

// Insert data into the table
$query = "INSERT INTO users (username, email) VALUES ('john_doe', 'john@example.com')";
$db->exec($query);

// Retrieve data from the table
$results = $db->query("SELECT * FROM users");
while ($row = $results->fetchArray()) {
    echo "ID: " . $row['id'] . ", Username: " . $row['username'] . ", Email: " . $row['email'] . "<br>";
}

// Close the database connection
$db->close();
