Login php

Se ho capito bene... vorresti concatenare le due stringhe?

input.html

<form action="string.php" method="POST">
<input type="text" name="username">
<input type="password" name="password">
<input type="submit" value="Esegui" name="esegui">
</form> 

string.php

$stringa = $_POST['username'] . $_POST['password'];
