Can't connect to MySQL via PHP

Hello all. I used the code below successfully to connect to a MySQL db on one hosting provider. I've moved the code to a new hosting provider with new values and it returns: Access denied for user 'user'@'db.hostprovider.net' (using password: YES) Even though I can copy and paste these three values (host, user and pass) and paste into Navicat to make a connection. So the credentials are correct, but they are not authenticating when used in PHP. I've tried making host "localhost" and "127.0.0.1"… both with the same result. Can someone tell me what I am doing wrong here? Appreciate it. Thanks, --Rick $db_name = "mydb"; $vc_host = "db.hostprovider.net"; $vc_user = "user"; $vc_pass = "pass"; $connection = @mysql_connect($vc_host, $vc_user, $vc_pass); $db = mysql_select_db($db_name, $connection); echo mysql_error();
