If you wish to use this code on your site, for your forums be sure to replace forums.killagraphix.com with your boards url for eg. yourdomain.com/forum/

I know this isn't a php script but I thought I'd paste it here any how.

[color=\"red\"]Seeing how a lot of you use phpbb forums I thought I'd post this:[/color]

Let's take a look at the phpBB table phpBB_users; you'll see a list
of fields. The fields we need are:
-> username
-> user_posts
What we are going to do is:
-> Get username & user's post count from the database
-> Get the next username & user's post count
-> Compare them
-> If the second user's post count is bigger, get put username & post count
into a variable and compare it with the next record.

Code: Select all

<?php 
 &nbsp; &nbsp;&#036;username &nbsp; &nbsp;= 'username'; 
 &nbsp; &nbsp;&#036;password &nbsp; &nbsp; = 'password'; 
 &nbsp; &nbsp;&#036;host &nbsp; &nbsp; &nbsp; &nbsp;= 'localhost'; 
 &nbsp; &nbsp;&#036;connection = mysql_connect &#40;&#036;username, &#036;password, &#036;host&#41;; &nbsp; &nbsp;//Create a MySQL 
connection 

 &nbsp; &nbsp;&#036;query = 'SELECT * from phpbb_users'; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //Create the query 

 &nbsp; &nbsp;&#036;result = mysql_db_query &#40;&#036;db, &#036;query, &#036;connection&#41;; &nbsp; &nbsp; &nbsp; &nbsp;//Run the query on 
the database 

 &nbsp; &nbsp;&#036;user1_posts &nbsp; &nbsp; = &#036;row&#91;'0'&#93;; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;//Create 2 empty variables to compare 
 &nbsp; &nbsp;&#036;user1_name &nbsp; &nbsp; &nbsp; &nbsp;= &#036;row&#91;'0'&#93;; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;//the usernames & post counts 

 &nbsp; &nbsp;while &#40;&#036;row = mysql_fetch_array&#40;&#036;result&#41;&#41; { &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;//Fetch the results from var 
&#036;result 
 &nbsp; &nbsp; &nbsp; &nbsp;&#036;user2_posts &nbsp; &nbsp; = &#036;row&#91;'user_posts'&#93;; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;//Put the username & post count into 
an temporary variable 
 &nbsp; &nbsp; &nbsp; &nbsp;&#036;user2_name &nbsp; &nbsp;= &#036;row&#91;'username'&#93;; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// 
 &nbsp; &nbsp; &nbsp; &nbsp;if &#40;&#036;user2_posts > &#036;user1_posts&#41; { &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;//Compare the post counts 
 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&#036;user1_posts &nbsp; &nbsp; = &#036;row&#91;'user_posts'&#93;; &nbsp; &nbsp; &nbsp; &nbsp;//If the new one is bigger, replace 
the old one with the new one 
 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&#036;user1_name &nbsp; &nbsp;= &#036;row&#91;'username'&#93;; 
 &nbsp; &nbsp; &nbsp; &nbsp;} 
 &nbsp; &nbsp;} 

 &nbsp; &nbsp;print &#40;'Top poster&#58; ' . &#036;user1_name . ' with ' . &#036;user1_posts . '.'&#41;; 
?>

That's it!

Browser Redirect:

Alright, this is a simple little script which will take you to one page if you're using Internet Explorer, and another page if you're using some other browser. Lets decide what this is going to do in English:

If the browser is MicroSoft Internet Explorer (MSIE), then go to spoono.com
If the browser isn't MSIE, then redirect to yahoo.com.

The most essential part of this is that this code has to be sent out before any output to the HTML page. Make sure it is the first line of code on your PHP page. With that said, here is the PHP:

<?
//if its MSIE then
if (&#036;name = strstr (&#036;HTTP_USER_AGENT, "MSIE"))
{
//go to Spoono
Header ("Location: http://www.spoono.com/");
}
else
{
//else go to Yahoo
Header ("Location: http://www.yahoo.com/");
}
?>
