I have this problem when I am trying to run my PHP MySQL script. When I try to run my .php file this is what I get.
mysql_connect(): No connection could be m
It looks like you forgot to add your password to your connection. Also, you should not use mysql connect anymore as it is officially depreciated. Use MYSQLi or PDO instead. An example of this would be:
$connection= mysqli_connect("localhost", "root", "password", "database")
or die(mysqli_error("error connecting to database"));
