The reverse of wp_insert_post

by

You’re looking for wp_delete_post.

<?php
$some_post_id = 1;
wp_delete_post($some_post_id);

The above will delete the post with ID 1 — well, it will actually set it to a “trash” status. You can delete the post for real by setting the second parameter of wp_delete_post to true.

<?php
$some_post_id = 1;
wp_delete_post($some_post_id, true); // really deletes the post
