What are best practices for naming variables in PHP forms?

When naming variables in PHP forms, it is important to choose clear and descriptive names that accurately represent the data being collected. Avoid using generic names like "data" or "value" and instead opt for specific names that indicate the purpose of the variable. Additionally, consider using camelCase or snake_case naming conventions for consistency and readability. 

// Example of naming variables in a PHP form
$firstName = $_POST['first_name'];
$lastName = $_POST['last_name'];
$emailAddress = $_POST['email'];
$phoneNumber = $_POST['phone_number'];
