How can PHP developers leverage PHP Data Objects (PDO) for better database interaction and security in their applications, as suggested in the forum thread?

PHP developers can leverage PHP Data Objects (PDO) for better database interaction and security in their applications by using prepared statements. Prepared statements help prevent SQL injection attacks by separating SQL logic from user input, thus ensuring that input is properly escaped and sanitized before being executed. This approach also improves performance by allowing the database to optimize the query execution plan. 

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

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

// Bind the parameter value to the named parameter
$stmt->bindParam(':username', $username);

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

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