Include it wherever you want the comments to appear. So if you include it in the head, then your comments will display before the rest of your site. Typically, webmasters put them at the bottom of the article or blog.

Also I notice you said HTML page; I just want to remind you that your pages should have a .php extension to be able to execute PHP coding.

If you want to display all comments, Just Modify the query: SELECT * FROM `comments` ORDER BY `date` ASC. Something like that would show the latest. Since the table in the DB holds the URL, you could display a link to each like this:

<a href="< ;? echo($result-&g t;url);?>&q uot; title="&l t;? echo($result-&g t;title); ?>"> ; <? echo($result-&g t;title); ?> </a>

something like that. That would be inside a while loop where $result = mysql_fetch_obj ect($query)

Now if I just want the comments to show up per entry as opposed to all at once, when I put the code under each entry the comments for that entry won't come up for any other entry, right?

And if I have existing HTML pages that require the comments, can I simply rename them to be .PHP files, or do I need to add something to the existing pages to make them PHP friendly?

Yea, like this site - I have 1 script that is designed to show articles, based on the ID passed to it. So in the script, the query will select the article from the database where id = xx.

When someone comments on a page, that unique URL is stored. So if someone comments on page 2 of article 1, then the comments script will only show those comments when your on that specific page of that specific article.

You should be able to change it to a .php extension no problem, give it a shot, test the stuff out. One thing is, if your blogs or pages (whatever you're wanting comments on) are static - meaning you manually created an HTML page for each one, then you will have to insert the comments script on each of those pages you want to allow comments. If that's the case, I would considering learning more about PHP and store your articles/blogs in a database, and design a script to fetch them dynamically.
