How can the issue of form data still being displayed after session destruction be prevented in PHP?

Issue: The issue of form data still being displayed after session destruction can be prevented by ensuring that the form fields are cleared or reset after the session is destroyed. This can be done by setting the form field values to empty strings or null values.

// Start the session
session_start();

// Destroy the session
session_destroy();

// Clear form data by setting form field values to empty strings
$form_field1 = "";
$form_field2 = "";
$form_field3 = "";
