What are some common pitfalls when using prepared statements in PHP?

One common pitfall when using prepared statements in PHP is not properly binding parameters, which can leave the application vulnerable to SQL injection attacks. To solve this issue, make sure to bind all parameters using the appropriate data type. Example: 

$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");

// Bind parameters with data type
$stmt->bindParam(':username', $username, PDO::PARAM_STR);

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