apply_filters_ref_array( 'post_limits', string $limits, WP_Query $query )

More Information

• This filter applies to the LIMIT clause of the query before the query is sent to the database, allowing you to define a new query LIMIT.
• You can return null to remove the LIMIT clause from the query, allowing you to return all results. However, this will set $wp_query->found_posts to 0.
• On some server environments, the LIMIT will be applied to all queries on the page. This results in menu items and widgets also being limited to the defined number. To only limit the number of posts on a page use the action hook pre_get_posts.
