Localhost不显示数据

So I've created a php file and I'm trying to connect to my database:

    <html>
    <head>
    </head>
    <body>

    <?php
    $con = mysql_connect ("localhost","Densino","password");
    if (!$con){
    die("cannot connect: " . mysql_error());    
    }
    echo 'connected successfully';

    mysql_close($con);



    ?>

    </body>
    </html>

But when I go to the localhost there is no data to be seen. The php file is saved in the www folder of wamp too,.So i'm at a total lose.

I've even followed a tutorial on youtube, where that code is from and it works perfect for him.

Any help is appreciated. This is what I see when I run localhost and click into the folder INDEX

I created a new folder for my projects in WWW.. and I ran the folder in the browser: http://Localhost/projects

This created a new index file in the folder which allowed me to view my php scripts

Thanks for the help and guidance guys
