<?php
$con = mysql_connect("localhost","root","");
mysql_select_db("databasename");
$strSQL1 = "SELECT * FROM test WHERE id_user = '1' ";
$objQuery1 = mysql_query($strSQL1);
$objResult1 = mysql_fetch_array($objQuery1);
$setTime = $objResult1 ['TIMEOUT'];

$date = strtotime($setTime);
$remaining = $date - time();

$days_remaining = floor($remaining / 86400);
$hours_remaining = floor(($remaining % 86400) / 3600);
echo "There are $days_remaining days and $hours_remaining hours left";
?>
