How can the PHP script be optimized for better performance and efficiency when processing file uploads and database entries?

To optimize the PHP script for better performance and efficiency when processing file uploads and database entries, it is important to handle file uploads asynchronously, use prepared statements for database queries to prevent SQL injection, and implement proper error handling to gracefully handle any issues that may arise. 

// Asynchronously handle file uploads
if(isset($_FILES['file'])) {
    move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
}

// Use prepared statements for database queries
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);
$stmt->execute();

// Implement proper error handling
try {
    // Your database query or file upload code here
} catch (Exception $e) {
    // Handle any errors or exceptions
    echo 'An error occurred: ' . $e->getMessage();
}
