Display limited output from mysql query

I want to do the following:
1-The user search for certain item.
2-Server run sql search.
3-Display the output of the search by showing 25,50, or 100 output per page as per the user choice.
For number 1, and 2 I do that easily by php, but for number 3, I am not sure how to accomplish this, is server side or client to show only a selected number of output, can some guide me how to do so?

use LIMIT into the query. Like this:

$sql= 'SELECT * FROM table LIMIT 5';

will fetch only 5 first records.

$sql= 'SELECT * FROM table LIMIT 5 10';

will fetch 10 records starting from 5.

The query part is not difficult, but the display part is not clear to me.
Let us say the search result return x output, and the use chose to see 25 output in one page, then depending on x will be the number of pages if x is 100 then we need 4 pages when the user press next he will to the next page, or if he press let us 3 he will jump to page 3.
Shall I make a full query, and put in an array and dsiplay it dynamically, or each time I need to make a query for each page.
Is there any example for that?

Hi, let's say you the current page is $page (starting with 1), and the requested number of records is $records.
This code should suit your needs :
// these values should be taken from GET/POST
$page = 1;
$records = 10;

// compute the SQL start number
$start = ($page-1) * $records;

// fetch the records
$res = mysql_query("SELECT SQL_CALC_FOUND_ROWS * FROM table LIMIT $start, $records");

// get the total number of records in the table
list ($total) = mysql_fetch_row(mysql_unbuffered_query("SELECT FOUND_ROWS()"));

// compute the number of pages
// you will use this number to display links to other pages
$pages = (($total - 1) - (($total - 1) % $records)) / $records + 1;

// now you can fetch your records with mysql_fetch_*($res);
