PHP Code:
<?
$day = date("z");
include ("galleries/$day.php");
?>
This is from a really simple site I did once, with a folder called galleries which included 366 files each containing 20 reviewed hosted galleries.
In a format like this
PHP Code:
<?php
$today = date("d-M");
print "$today";
?> ~ <a href="http://galleries.whatever.com/?422">Hardcore gallery description</a><br>
Each set of 20 would be on a page called...
0.php
1.php
>>
365.php
It ain't the best way of doing it, but it works.
