How can PHP be used to display relevant articles first in WordPress?

To display relevant articles first in WordPress, you can use PHP to modify the query parameters to prioritize relevant content based on certain criteria such as tags, categories, or custom fields. One way to achieve this is by using the pre_get_posts hook to alter the main query before it is executed. 

function custom_order_query($query) {
    if ( !is_admin() && $query->is_main_query() && is_home() ) {
        $query->set('orderby', 'relevance'); // Set the order by relevance
    }
}
add_action('pre_get_posts', 'custom_order_query');
