Error Connecting to DataBase!: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES)

I recently set up a local WAMP Server (my first ever so please mind the vertical learning curve)

    Apache Version: 2.4.27
    PHP Version: 5.6.31
    Server Software: Apache/2.4.27 (Win64) PHP/5.6.31 - Port defined for Apache: 80
    MySQL Version: 5.7.19 - Port defined for MySQL: 3306
I installed using the default settings. Including no password on the root directory.

mysql> show grants for root@localhost;
mysql> SELECT User, Host, HEX(authentication_string) FROM mysql.user;
| User          | Host      | HEX(authentication_string)                                                         |
| root          | localhost |                                                                                    |
| mysql.session | localhost | 2A5448495349534E4F544156414C494450415353574F52445448415443414E42455553454448 |
| mysql.sys     | localhost | 2A5448495349534E4F544156414C494450415353574F52445448415443414E42455553454448|
I imported an existing database from a public shared server into the db and moved the public_html files for the website into a sub-directory of the WAMP directory.

The website I've migrated across requires the user enter a password to access the url. The site itself also requires a user name and p/w.

I removed the URL p/w access by not migrating the .htaccess file across.
I then modified the website and database files to reflect the localhost settings.

//echo " loading; ";
$mysqli = mysqli_connect($server, $user, NULL, $database);
if (!$mysqli) {
    die('Could not connect: ' . mysql_error());
try { $pdom = new PDO("mysql:host=$server;dbname=$database", $user, $password); }
catch (PDOException $e) { print "Error Connecting to DataBase!: " . $e->getMessage() . "<br>"; die(); }
//echo 'Connected successfully';


$mysql = mysqli_connect('localhost', 'root', 'NULL');
/* Test the MySQL connection */
if (mysqli_connect_errno()) {
printf("Connection failed: %s\n", mysqli_connect_error());
/* Print the MySQL server version */
printf("MySQL server version: %s\n", mysqli_get_server_info($mysql));
/* Close the MySQL connection */
c://WAMP64/www/possbil contains:
    html directory and files
c://WAMP64/www/private contains:
I have 2 problems:

When I follow the "possbil" directory link from the WAMP (localhost) GUI instead of opening the website as expected I get an error:

"possbil’s server DNS address could not be found."

Specifically defining the DNS server setting (Windows 10) doesn't fix this issue -
    Preferred DNS server :
    Alternate DNS server :
If I manually enter the url "locahost/possbil/" in the browser. I get the error:

"Error Connecting to DataBase!: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES)"

From the documentation this seems to imply that I'm somehow passing in a password for the user "root". And because there is no password set it is bouncing?

Assuming my thinking is even on the right page here, I'm a bit stumped where the password is coming from?

I know there is no password for the root user set, and from what I can grasp of php so far using "NULL"in the file should not be getting read as as a script?

I will be the only one using the local version so prefer not to have a password set.

Anyhow welcome any guidance on where to look next.
