What are the best practices for coding a custom database for file storage in PHP?

When coding a custom database for file storage in PHP, it is important to follow best practices to ensure efficiency and security. One key practice is to properly sanitize user input to prevent SQL injection attacks. Additionally, use prepared statements to prevent SQL injection and improve performance. Finally, consider implementing encryption for sensitive data to enhance security. 

// Example of using prepared statements with PDO for file storage in PHP

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=files_db', 'username', 'password');

// Prepare a SQL statement
$stmt = $pdo->prepare("INSERT INTO files (file_name, file_data) VALUES (:file_name, :file_data)");

// Bind parameters
$stmt->bindParam(':file_name', $file_name);
$stmt->bindParam(':file_data', $file_data, PDO::PARAM_LOB);

// Execute the statement
$stmt->execute();

// Close the connection
$pdo = null;
