Pagination is only changing the page number, not the content - php

Question

I have a table with a list of users and I want to create pagination for this table.
However, when I click page number 2 the page changes but not the contents of the list of users.
<?php
session_start();
require_once "connect.php";
//Database connect
$database = #new mysqli($host, $db_user, $db_password, $db_name);
//Limit users
$start = 0;
$limit = 3;
//Question to -> Database
$sql = ("SELECT * FROM users LIMIT $start, $limit");
$adds = $database->query($sql);
//Return records
$rows = mysqli_num_rows($adds);
echo "Rows found in database.. ".$rows."<br /><br />";
if(isset($_GET['id']))
{
$id=$_GET['id'];
$start=($id-1)*$limit;
}
else{
$id=1;
}
if ($rows >= 1)
{
//the beginning of the table
echo<<<END
<table width="1000" align="center" border="1" bordercolor="#d5d5d5" cellpadding="0" cellspacing="0">
<tr>
<td width="50" align="center" bgcolor="e5e5e5"></td>
<td width="50" align="center" bgcolor="e5e5e5">IDUsera</td>
<td width="20" align="center" bgcolor="e5e5e5">NazwaUsera</td>
<td width="20" align="center" bgcolor="e5e5e5">EmailUsera</td>
<td width="20" align="center" bgcolor="e5e5e5">DataRejestracji</td>
<td width="20" align="center" bgcolor="e5e5e5">Indetyfikator grupy</td>
</tr>
<tr>
END;
}
while($score = mysqli_fetch_assoc($adds)) {
$row_score_id = $score['id'];
$row_score_user = $score['user']." ";
$row_score_register = $score['dataRes']. " ";
//continued table
echo<<<END
<td width="50" align="center"><a class="button_red" href="delete_user.php?id=''">Delete</a></td>
<td width="50" align="center">$row_score_id</td>
<td width="100" align="center">$row_score_user</td>
<td width="100" align="center"></td>
<td width="100" align="center">$row_score_register</td>
<td width="100" align="center"></td>
</tr>
END;
}
$pagnSql = ("SELECT * FROM users");
$pagnBase = $database->query($pagnSql);
$pagnRows = mysqli_num_rows($pagnBase);
$total=ceil($pagnRows/$limit);
if($id>1)
{
//Go to previous page to show previous 10 items. If its in page 1 then it is inactive
echo "<a href='?id=".($id-1)."' class='button'>PREVIOUS</a>";
}
if($id!=$total)
{
////Go to previous page to show next 10 items.
echo "<a href='?id=".($id+1)."' class='button'>NEXT</a>";
}
for($i=1;$i<=$total;$i++)
{
if($i==$id) { echo "<li class='current'>".$i."</li>"; }
else { echo "<li><a href='?id=".$i."'>".$i."</a></li>"; }
}
?>

Answer 1

You have to put the $start from GET
Change this
$start = 0;
To:
$start = $_GET[id];
