What are the best practices for sorting WordPress articles based on custom fields in PHP?

When sorting WordPress articles based on custom fields in PHP, it is best to use the `WP_Query` class with the `meta_key` and `orderby` parameters. By specifying the custom field key in `meta_key` and the desired sort order in `orderby`, you can effectively sort the articles based on the custom field values. 

$args = array(
    'post_type' => 'post',
    'meta_key' => 'custom_field_key',
    'orderby' => 'meta_value',
    'order' => 'ASC'
);

$query = new WP_Query($args);

if($query->have_posts()) {
    while($query->have_posts()) {
        $query->the_post();
        // Display your article content here
    }
} else {
    // No posts found
}

wp_reset_postdata();
