I'm learning PHP & MySQL. While trying to folllow a tutorial I am not getting the erxpected result which is simply to retrieve a little data out of a table with a query.
Here is my PHP code:

<?php
//1. Create a database connection
$connection = mysql_connect("localhost", "kingdomc_mtech", "busine$$");
if (!$connection)
{
die("Database connection failed: " . mysql_error());
}

//2. Select a database to use
$db_select = mysql_select_db("kingdomc_learning", $connection);
if (!$db_select)
{
die ("Database selection failed: " . mysql_error());
}
?>

<body>
<?php
	//3. Perform database query
	$result = mysql_query("SELECT * FROM subjects", $connection);
	if(!$result)
	{
	die ("Database query failed: " . mysql_error());
	}
	//4. Use returned data
	while ($row = mysql_fetch_array($result));
	{
	echo $row[0]." ".$row[2]."<br/>";
	}
	?>
</body>
</html>
<?php
//5. Close connection
mysql_close($connection);
?>

and i have attached a screenshot of my very simple table. Thanks for the time and help.

No error message. I'm not getting any data returned. When I load and even refresh my page its just blank.
