Are there any potential pitfalls to be aware of when using prepared statements in PHP?

One potential pitfall to be aware of when using prepared statements in PHP is not properly binding parameters, which can lead to SQL injection attacks. To mitigate this risk, always ensure that you bind parameters correctly when executing prepared statements. 

// Example of using prepared statements in PHP with proper parameter binding

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

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

// Bind parameters
$username = 'example_user';
$stmt->bindParam(':username', $username, PDO::PARAM_STR);

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

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

// Loop through results
foreach ($results as $row) {
    // Process each row as needed
}
