How can changes in server-side scripts affect the functionality of a PHP form?

Changes in server-side scripts can affect the functionality of a PHP form by causing errors in data processing, validation, or submission. To ensure the form functions correctly, it is important to update the server-side scripts accordingly whenever changes are made. This includes adjusting variables, functions, and logic to align with the new requirements or modifications.
