What are the potential issues with binding parameters in PHP when submitting form data?

One potential issue with binding parameters in PHP when submitting form data is that if the form data contains user input that is not properly sanitized, it could lead to SQL injection attacks. To solve this issue, it is important to always sanitize and validate user input before binding it to parameters in SQL queries. 

// Example of sanitizing and binding form data in PHP
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);

$stmt = $pdo->prepare("INSERT INTO users (name, email) VALUES (:name, :email)");
$stmt->bindParam(':name', $name, PDO::PARAM_STR);
$stmt->bindParam(':email', $email, PDO::PARAM_STR);
$stmt->execute();
