Change the way you include mylogin.php file like given in below code: And there won't be this problem.

Welcome

<h1> Please login</h1>
<br>

<!--
<form action="" method="POST">
<label>Username: </label><br>
<input type="text" name="username" placeholder="Enter username"/><br>
<label>Password: </label><br>
<input type="password" name="password" placeholder="Enter password"/><br><br>
<input type="submit" name="submit" value="Login"/><br><br>
</form>
-->

<form method="post" action="">
<label>Username:</label><br>
<input type="text" name="username" placeholder="username" /><br><br>
<label>Password:</label><br>
<input type="password" name="password" placeholder="password" />  <br><br>
<input type="submit" name="submit" value="Login" /> 
</form>

</body>
</html>

<?php
if(isset($_POST["submit"]))
{
    include("mylogin.php");
}
?>

And of course, change your if condition of your mylogin.php file like this:

if(isset($_POST["submit"])) OR you can change it 
if(!empty($_POST["submit"]))

You got a trouble with this condition if(empty($_POST["submit"])). You want the negative condition of this, so you need something like :

if(!empty($_POST["submit"])) (with !)
