<body>
<?php
error_reporting(0);
include("config.php");
$quer= "SELECT*FROM ".$db_table." ";
$query=mysqli_query($connect,$quer)
or die(mysqli_error());
?>
<?php while($row = mysqli_fetch_array($query)):
setcookie("$cookiename", $row, 2 * 24 * 60 * 60 * 1000);
//i do not know how can i retrieve columns now
