What are best practices for handling data retrieval from .db files in PHP?

When retrieving data from .db files in PHP, it is best practice to use SQLite functions to interact with the database. This ensures proper handling of the data and prevents SQL injection attacks. Additionally, it is recommended to sanitize user input before executing queries to further protect against security vulnerabilities. 

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

// Sanitize user input
$user_input = SQLite3::escapeString($user_input);

// Execute a query to retrieve data
$query = $db->query("SELECT * FROM your_table WHERE column = '$user_input'");

// Loop through the results
while ($row = $query->fetchArray()) {
    // Process the retrieved data
}

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