multiple headers & footer

hi,
im beginning to create project with Arabic and English language,
I’ve created header-en.php for English pages and header-ar.php for Arabic pages,
I asked this question before.. the answer it was to use multiple header use this code:
$h = get_post_meta($post->ID, ‘header_language’, true);
if($h==’en’){
get_header( ‘en’ );
}elseif($h==’ar’){
get_header( ‘ar’ );
}else{
get_header();
}
I’ve already paste this code to page.php and not worked,
also I tried to use this code:

if ( is_home() ) :
get_header( ‘en’ );
elseif ( is_404() ) :
get_header( ‘404’ );
else :
get_header();
endif;
the second code that I tried its worked on the home page only, but what about pages created on the admin pages screen on wordpress and how to use page ID to get the header-en.php or header-ar.php
so my first question how to use multiple headers and working on the pages id ?
my second question is that found alternative for page.php and index.php?
because I need to make home page for Arabic and home page for English..
please I need help I’ve to finish the website and review it for client after two days ago..
many thanks for wordpress members and team
best regards..
