There is a problem with my db table. For example i send 6 posts (with title, author and content) to the db table one after an other, so their post's id would be 1-2-3-4-5-6.
Then if i delete the post number 6 and then write a new post (which it's id must be 7), after that when i echo all posts on the page to see them, i see posts with ids 1-2-3-4-5-7 !!
How can i solve this problem? When i delete the post with id 6, the next post should be set there into id 6.
