Hello, I just installed XAMPP to a Windows 7 computer and I am trying to learn some PHP. I go to C:/xampp/htdocs and create a file named phptest.php. And I write inside this code :

<HTML>
<HEAD>
<TITLE>PHP Testing</TITLE>
</HEAD>
<BODY>
<?php
echo “If this works, we <i>really</i> did it!”;
?>
</BODY>
</HTML>

And I go to http://localhost/phptest.php I get the code itself not the desired sentence. Can you tell what I am doing wrong?
Thank you very much.
