Different logo and footer on different page Id’s

Thank you so much! I’m not sure were to insert that code into php.

Please see a copy of the 1st lines of code in there now. Could you tell me where to insert?

<?php
if( ! defined( ‘ABSPATH’ ) ) { die(); }

global $avia_config;

if( ! is_array( $avia_config ) )
{
$avia_config = array();
}
