"Notice: Undefined variable: sql ... " means that you are trying to use a variable that doesn't exist or is not defined at that moment.

Try defining the $sql variable at the beginning of the file where your database connection is.

That code above means that you are trying to use a variable before it actually has a value in it. You need to make sure $sql has a value when it is being used.

SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES)

That means that your used credentials are wrong and the connection to the database is refused. Make sure you use the right credentials that you have set in phpMyadmin.
