$sql = mysqli_query($conn, "SELECT course_id FROM courses");
$total_records = mysqli_num_rows($sql);
$limit = 10;
$total_pages = ceil($total_records / $limit);

//start pagination
$PaginationLinks = "<ul class='pagination'>";

for ($i=1; $i<=$total_pages; $i++) {
$PaginationLinks .= "<li><a href='".$_SERVER['PHP_SELF']."?page=".$i."' class='link' onclick='getResults(".$i.")'>".$i."</a></li>";

$(document).ready(function(){
$(".link").click(function(e){
e.preventDefault();
});
});

function getResults(page) {
$.ajax({
type: "GET",
url: "result.php",
data: {page : page},
cache: false,
success: function(html) {
$("#content").html(html);
}
});
}

//default homepage content loading
getResults(1);
</script>

<?php  
include_once 'config.php';
$limit = 10;
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$start_from = ($page-1) * $limit;
$sql = mysqli_query($conn, "SELECT * FROM courses LIMIT $start_from, $limit");
?>

<table class="table table-bordered table-striped">
<thead>
<tr><th>ID</th><th>Name</th></tr>
<thead>
<tbody>
<?php while($row = mysqli_fetch_array($sql)) {
?>
<tr>
<td><?php echo $row["course_id"]; ?></td>
<td><?php echo $row["course_name"]; ?></td>
</tr>
