This will return your MySQL query as an array and a search map made up of previous/next buttons, select sub-page combo-box and a records per page combo box.

Name of Script: Search navigation
Version: 1.0
Author: Matthew Lindley
E-mail: sir_tripod@hotmail.com
Notes:
I've created this simple search navigation script so you can search through your database with using only one SQL query.
The form offers a previous/next buttons and combo-boxes to jump to a sub-page as well as set number of records to show per page.
There's a commented example of how to use this script at the bottom.
The best way (I think) to add this to a page is to include() it.
Please send me an e-mail to say you've downloaded it: sir_tripod@hotmail.com That's all.
No registration. No costs. No headaches in getting code to work. Just one email.
Also, I cannot and will not be held resposible for any (mis)use of this script. It's tested safe but please test it yourself first before running it properly.
If the script doesn't work, you may need to alter the REGISTER_GLOBALS setting in your php.ini file.

Building a software-as-a-service solution requires addressing a few key technical challenges. In this webcast, we'll focus on the role of IBM Tivoli Directory Server and WebSphere Portlet Factory in creating a Software as a Service solution. We will demonstrate how to use Tivoli Directory Server to prevent the user population of one tenant from accessing the virtual portal and portlet components of another tenant. We will also use the dynamic profile capability of WebSphere Portlet Factory to create multiple highly customized applications from one code base.
