Parse the table in php

1

Hello guys, I am really new at this and I have connected the mysql server two or three times before but this time I just cannot succeed.


<html>
<head>
<body>
<?php
    $server= "localhost"; //ie: mysql.server.net
    $username = "edna"; //ie: jonnhy
    $password = "cow"; //ie: password101
    $databasename = "blog_db"; //ie: jonnydata
    $tablename= "blog_entries"; //ie: emails
    $connection = mysql_connect("$server","$username","$password");
    if(!$connection)// are we not connected?
    {
    echo "Couldn't make a connection!!!";
    exit; //exits the script
    }
    $db = mysql_select_db("$databasename",$connection);
    if(!$db) //was the database not found?
    {
    echo "The database disapeared!";
    mysql_close($connection); //closes connection
    exit; // exits the code
    }
    echo "If you can see this you are connected to your database and your table is selected.";

?>
</body>
</html>

here as you see I am connecting it via a nice snipplet though I don’t get anything in the browser.

I make sure the database name the table name the user name the pass is true.

is there any error in this code?
