<?php
session_start();
?>
<?php
define('DB_HOST', 'localhost');
 define('DB_NAME', 'app');
 define('DB_USER','root');
 define('DB_PASSWORD','');
 $con=mysqli_connect(DB_HOST,DB_USER,DB_PASSWORD,DB_NAME) or die("Failed to connect to MySQL: " . mysqli_error());
mysqli_error());
 function SignIn()
 {
}
if(isset($_POST['submit']))
{
 if(!empty($_POST['username']))
{
$username = $_POST['username'];
$psw = $_POST['psw'];
 $q = mysqli_query($con,"SELECT `id`, `username`, `email`, `country`, `psw`, `address`, `phone`, `days`, `months`, `dob` FROM `databasee` WHERE username = '$username'") or die(mysqli_error());
 
$row = mysqli_fetch_array($q) or die (mysqli_connect_error());
if(password_verify($_POST["psw"],$row['psw']))
{
$_SESSION['username'] = $username;
echo " Username:".$row['username']." ";
