What are the limitations of using unset($_POST) to reset $_POST variables?

Using unset($_POST) to reset $_POST variables is not recommended as it can lead to unexpected behavior and potential security vulnerabilities. Instead, a safer approach is to manually unset individual $_POST variables that need to be reset. 

// Unset individual $_POST variables
unset($_POST['variable1']);
unset($_POST['variable2']);
// Continue unsetting other variables as needed
