What are the potential pitfalls of using prepared statements in PHP when inserting data into a database?

One potential pitfall of using prepared statements in PHP when inserting data into a database is not properly binding the parameters, which can lead to SQL injection attacks. To solve this issue, make sure to bind all parameters securely before executing the prepared statement. 

// Example of using prepared statements in PHP to securely insert data into a database

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

// Prepare the SQL statement with placeholders
$stmt = $pdo->prepare("INSERT INTO users (username, email) VALUES (:username, :email)");

// Bind the parameters securely
$stmt->bindParam(':username', $username, PDO::PARAM_STR);
$stmt->bindParam(':email', $email, PDO::PARAM_STR);

// Set the parameters
$username = "john_doe";
$email = "john.doe@example.com";

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