i have the server at localhost my database name is psnm, user is root and no password, can anybody please help me find out the problem…

Answer 1

The constructor of the PDO needs the dsn as the first parameter. Look the syntax below:

PDO::__construct() ( string $dsn [, string $username [, string $password [, array $driver_options ]]] )

Please consult PHP manual for more information.
