Hi,
I want to make a page in which there will be number of pages listed according to items in the database ....like 2 items per page....10 items means five pages need to be shown with links. I have used looping and a difficult method to carry out this. It works but I feel that its not an efficient way...could increase the processing speed though I am not sure. I know that one can use LIMIT (mysql) for this. Also I need to show like 1,2,3,4,5 Next and in next page Previous 6,7,8,9,10. I havent worked with the LIMIT thing so was seeking out some help.

As always, i suggest for this 'Helper' Class which you can use it for any pages(nicely explained):

There are also other pagination links:

$_URL?
Don't you mean $_REQUEST or $_GET?
Anyhow, you must intval() the page number, you don't want funny things happening with it, right? :)
the query is by the way:
$pageID = (isset($_REQUEST['pageID']
$recordsPerPage = 10;
$firstRec = ($pageID-1)*$recordsPerPag
$sql = "SELECT * FROM table ORDER BY id LIMIT {$firstRec}, {$recordsPerPage};";
There isn't a much more efficient way to do it. This sends 1 query and fetches only the relevant records.
You can of course fetch all the DB to a Session, and then only read it from there, but... come on, that's just heavy on the server.

Here's a bit of code that may help you out. This doesn't get into displaying 1 2 3 4 5 but it will point you in the right direction. To display all the available pages, you'd have to get the total number of results and then just calculate how many pages there will be and display the links.
<?php
if($_URL['pageID']=="") {
$pageID = 1;
}
$numItemsPerPage = 5;
$sql = "SELECT * FROM stuff LIMIT " .($pageID*$numItemsPerPage
//run the sql
//output your results
echo "<a href='myPage.php?pageID=".
?>
