pagination calculation

[Michdd]

I need something that will set $start = "0", $end = "25" if $page isn't set (default) like...

 

$page = $_REQUEST['page'];
if(!isset($page)){
$page = "1";
}

 

But then if page is set it must set things like this example:

 

if($page == "2"){
$start = "25";
$end = "50";
} elseif($page == "3"){
$start = "50";
$end = "75
}

 

And so on..

Something like this?

 

$page = $_REQUEST['page'];
if(!isset($page)){
   $page = "1";
} else {
   $start = ($page - 1) * 25;
   $end = $start + 25;
}

You can do this:

 

$page = (int) $_REQUEST['page'];
$start = ($page - 1) * 25;
$end = $start + 25;

$page = isset($_REQUEST['page'] ? $_REQUEST['page'] : 1;
$start = ($page - 1) * 25;

 

If you are paginating with MySQL you won't need $end. Just use

 

SELECT ........ LIMIT $start, 25
