What are the potential risks of using the extract function on form data in PHP?

Using the extract function on form data in PHP can potentially lead to security vulnerabilities such as variable injection and overwrite, making your code susceptible to malicious attacks. To mitigate this risk, it is recommended to manually assign form data to variables rather than using extract. 

// Assign form data to variables manually
$name = $_POST['name'];
$email = $_POST['email'];
$age = $_POST['age'];
