How to pass a language parameter to wp_nav_menu ?

Here is my current code…

// Create an array with all the languages, cleanded up
	$languages = pll_the_languages(array('raw'=>1));
	$menus = array();
	foreach($languages as $language) {
		//$current_language = $language['slug'];
		$theme_location = 'mobile-app-menu';
		$locations = get_nav_menu_locations();
		$menu_id = $locations[$theme_location];
		$menu_items = wp_get_nav_menu_items($menu_id);
		$menu = array();
		foreach ($menu_items as $menu_item) {
		    $trimmed_menu_item['object_id'] = $menu_item->object_id;
		    $trimmed_menu_item['menu_item_parent'] = $menu_item->menu_item_parent;
		    $trimmed_menu_item['menu_order'] = $menu_item->menu_order;
		    $trimmed_menu_item['title'] = $menu_item->title;
		    $trimmed_menu_item['description'] = $menu_item->description;
		    $trimmed_menu_item['post_status'] = $menu_item->post_status;
		    $trimmed_menu_item['object'] = $menu_item->object;
		    $trimmed_menu_item['url'] = $menu_item->url;
		    array_push($menu, $trimmed_menu_item);
		}
		array_push($menus, $menu);
	}
	return $menus;

Hi!

The correct nav_menu is stored in the ‘polylang’ option. You can get it with these keys:
['nav_menus'][$theme][$nav_menu_location][$language_slug]

Hi based on Chouby’s answer, here’s a simple function to get the menu ID based on the menu’s theme_location:

function get_language_menu_id( $theme_location = '' ) {
	// Check for theme location
	if ( $theme_location == '' )
		return 0;

	// Get Polylang options
	$options = get_option( 'polylang' );
	if ( $options && isset( $options['nav_menus']['your_theme_name'][ $theme_location ] ) ) {
		$current_language = pll_current_language();
		if ( isset( $options['nav_menus']['your_theme_name'][ $theme_location ][ $current_language ] ) )
			return $options['nav_menus']['your_theme_name'][ $theme_location ][ $current_language ];
	}

	// Something went wrong
	return 0;
}
