Answer 1

First You make sure that connection established correctly to the database.

Instead of writing query directly in

$check = mysql_query("SELECT * FROM Test WHERE username = '$username'");

Store the query in variable as

$query = "SELECT * FROM Test WHERE username = '".$username."'";

and execute it as

$check = mysql_query($query);

if you are still facing the issue,

echo the query as

echo $query;

and execute the query directly in phpmyadmin and you can find the issue.

I hope this helps.
