下一页/上一页错误

Question

I need some help, I want to make an next / previous page but I have some problems...

This is the PHP Code, how I try to make it. The problem is that it doesn't show 3 data on the first page and on the next page it puts the same data again an not the other one.

Code:

$statement = $connect->prepare("SELECT COUNT(*) AS anzahl FROM `accounts`");
$statement->execute();
$row = $statement->fetch();
$max_data = $row['anzahl'];

$page = 1;
if(isset($_GET['page'])) {
   $page = intval($_GET['page']);
}

$max_info = 3;
$start = ($page - 1) * $max_info;
$number_page = ceil($max_data / floatval($max_info));    

for($a = 1; $a <= $anzahl_seiten; $a++) {
   if($page == $a){
      echo " <b>$a</b> ";
   } 
   else {  
      echo " <a href='acp.php?page=list_all_player&seite=$a'>$a</a> ";
   }

}
