What are the potential security risks associated with dynamically creating text fields in a form using PHP, and how can these risks be mitigated?

Potential security risks associated with dynamically creating text fields in a form using PHP include the possibility of injection attacks, such as SQL injection or cross-site scripting (XSS). To mitigate these risks, it is important to properly sanitize and validate user input before using it in the dynamically created text fields. 

// Example code snippet to mitigate security risks by sanitizing and validating user input

// Sanitize and validate input before using it in dynamically created text fields
$name = isset($_POST['name']) ? htmlspecialchars($_POST['name']) : '';
$email = isset($_POST['email']) ? filter_var($_POST['email'], FILTER_SANITIZE_EMAIL) : '';

// Dynamically create text fields with sanitized input
echo '<input type="text" name="name" value="' . $name . '">';
echo '<input type="text" name="email" value="' . $email . '">';
