I'm not all too fond of .htaccess files, so I've chosen to stick to the server-side programming PHP and mySQL. So maybe you should wait for a confirming reply from a little bit more experienced scripter than me. For example, Karl, Salathe of Wildhoney.

On to the posted PHP field. I've checked it our and it should not pose any problem. I reckon it's for some kind game browser or progress page? I'm very fond of those scripts, so if you could share a little bit more, that would be very graceful.

Anyways, returning to the pagination part. There, since you said you were kind of a beginner, are a few ways to do pagination. Through classes or simple methods like $_GET[page] and LIMIT in the query. Simply use the TOTAL of results to generate a page.

For exmaple, you've got a limit of 20 results a page.

LIMIT 0 20
LIMIT 20 40
LIMIT 40 60
LIMIT 60 80

And so on. Now how do you get it dynamic? If NO $_GET is defined, LIMIT is simply 0 to $max ($max = 20;)
Then, if get is set, you can retrieve it (like $_GET[page] is 20), then you simply add it to $new = $_GET[page] + $max.
LIMIT '.$_GET[page].' '.$new.' :)

It should NOT pose any conflicts since the while loop simply echo'd what you retrieve, thus you choose WHAT to retrieve with the LIMITS.

Make sure to build in simply checks like if (!is_numeric($_GET[page])) {
exit('trying to be a h4xxOR!?');
}

DONE.

Good luck! Hopefully you kinda understand my jibberish up there.
