header("Location: /welcome.php", true, 301);

If header isn’t working it is because the php code is under the <!DOCTYPE html>. To resolve this, but the php code on the top of <!DOCTYPE html>

Example :

<?php // the code is on the start of the file
$con=mysqli_connect('localhost','id169218_venki','**********','id169218_mydb');
session_start();
if(isset($_POST['loginbtn'])){
$email=$_POST['email'];
$password=$_POST['pwd'];
$result=mysqli_query($con,'select * from myguests where email="'.$email.'" and password="'.$password.'"'); 
// mysqli is a bit outdated to be honest. consider using PDO
if(mysqli_num_rows($result)==1)
{
	$_SESSION['email']= $email;
	header("Location:welcome.php");
}
else
	die("INVALID ACCOUNT"); // Use the command die for dyin... uhh i mean display something and interrupt the code.
}

?>
<!DOCTYPE html>
<html>
<body>


</body>
</html>

Here you go :smiley: !
