$con = mysqli_connect("localhost","my_user","my_password","my_db");
$limit = 10;                
$query = "SELECT * FROM  $table";
$resource = mysqli_query($con,$query);
$total_rows = mysqli_num_rows($resource);
$start = $total_rows-$limit;
$query_limit= $query." LIMIT $start,$limit";

First I have set the limit

$limit = 10;

then

 $total_rows = mysqli_num_rows($resource);

Here I have taken total number of rows affected.

$start = $total_rows-$limit;

then substracted limit from number of rows to take starting record number

   $query_limit= $query." LIMIT $start,$limit";

and then added limit to the query. For more information about limit see this link https://www.w3schools.com/php/php_mysql_select_limit.asp
