How would I go about making a pagination script for this MySQL & PHP query.

if (isset($_GET[\'c\'])) {
$c = $_GET[\'c\'];
}

$query = mysql_query(\"SELEC

    First of all find out how many games are there for a specific category

    change the line

    $query2 = mysql_query("SELECT * FROM Games WHERE category = '$code' ");

    to

    $sql="SELECT * FROM Games WHERE category = '$code' ";
$query_count=mysql_query($sql);

    Add following after it

    $per_page =30;//define how many games for a page
$count = mysql_num_rows($query_count);
$pages = ceil($count/$per_page);

if($_GET['page']==""){
$page="1";
}else{
$page=$_GET['page'];
}
$start    = ($page - 1) * $per_page;
$sql     = $sql." LIMIT $start,$per_page";
$query2=mysql_query($sql);

    Then display the numbers of pages where you want

    <ul id="pagination">
        <?php
        //Show page links
        for ($i = 1; $i <= $pages; $i++)
          {?>
          <li id="<?php echo $i;?>"><a href="linktoyourfile?c=<?php echo $c;?>&page=<?php echo $i;?>"><?php echo $i;?></a></li>
          <?php           
          }
        ?>
      </ul>

    Use CSS for pagination this will do the trick

        Pagiantion, it is working simple and easy 
       <?php  
        $sql = "SELECT COUNT(id) FROM contact_info";

        $rs_result  = $conn->query($sql); 
        $row = mysqli_fetch_row($rs_result);  
        $total_records = $row[0]; 
        echo $total_records;
        $previous   = 1;
        $total_pages = ceil($total_records / $limit); 
        $next  = $_GET["page"] + 1;
        $previous  = $_GET["page"] - 1;
        $pagLink = "<span>"; 
        if($previous ==0)
        {
        $prev  = "<a href='javascript:void(0);' >Previous</a>";
        }
        else
        {
          $prev  = "<a href='http://homeacresfinefurniture.com/all-queries.php?page=".$previous."' style='color:black;'>Previous</a>";   
        };
        echo $prev;

        "</span><div class='pagination'>";
        for ($i=1; $i<=$total_pages; $i++) 
        {  
        $pagLink .= "<a href='http://homeacresfinefurniture.com/all-queries.php?page=".$i."'>".$i."</a>";  
        };  
        echo $pagLink;

        $nex  = "<span><a href='http://homeacresfinefurniture.com/all-queries.php?page=".$next."' style='color:black;'>Next</a></span>";
        echo $nex;

        ";
        </div>";
      ?>

    Get all data from database. 

                $limit = 1;  
            if (isset($_GET["page"])) 
            {
                $page  = $_GET["page"];
            }
            else 
            {
             $page=1; 
            }  
            $start_from = ($page-1) * $limit;     
            $sql = "SELECT * FROM contact_info ORDER BY id desc LIMIT $start_from , $limit";
