How can one ensure that the data transfer process in PHP is efficient and secure?

To ensure efficient and secure data transfer in PHP, one should use secure protocols like HTTPS, validate input data to prevent SQL injection attacks, and sanitize output data to prevent XSS attacks. Additionally, using prepared statements for database queries can help prevent SQL injection vulnerabilities. 

// Example of using prepared statements to securely transfer data in PHP

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare a SQL statement
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');

// Bind parameters
$stmt->bindParam(':username', $username);

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

// Fetch the results
$results = $stmt->fetchAll();
