Answer 1

You need to add simple if else statement.
if (isset($_POST['submit_form'])) {
// Your code after form get submitted.
}
else {
// Show default form.
}

Answer 2

Just load your HMTL Code in to your PHP as a kind of "Template" with file_get_contents(__DIR__ . "Path/To/Your.html"); in to a variable and do a simple str_replace('id="your_element_id"', 'id="replace_id"', $template_variable); and echo your Template after if you just want to replace an ID.
If you want to change something within the Form, do it as i said above with str_replace('tag_you_are_looking_for', 'should_be_replaced_with', $template_variable);
