Question

I’m trying to order a certain ID from highest to lowest.

Say, I have 5 id’s.

1
2
3
4
5

I’m trying to have it order my most recent/highest ID.

Like,

5
4
3
2
1

Here is the code that “posts” it (it’s for a blog, btw)

$post = mysql_query("SELECT * FROM blog ORDER BY id") or die(mysql_error());

I’m sure there is a way, but can’t understand how to very well.

You should have a look at arsort() and related functions from the PHP Manual: http://www.php.net/manual/en/function.arsort.php

This answer is assuming that you have put your values into an array: $foo[] = { 1, 3, 4, 2, 5 }; However, it is the general sentiment of the people watching this that you have not given enough information about your situation to properly answer the question. I can understand that viewpoint. Generally, you should include a slice of source code that concerns your specific question. Without that, you will probably be downvoted instead of given a proper answer. This is also a good way to show us that you are not simply having StackOverflow do your homework for you. 🙂

In MySQL, your statement should include the DESC keyword for “descending”:

$post = mysql_query("SELECT * FROM blog ORDER BY id DESC") or die(mysql_error());
