mysql_connect works, but mysqli_connect doesn't...

[ShootingBlanks]

When I use this code:

$link = mysql_connect($hostname_SalesRepository, 'rump888', $password_SalesRepository, 'salesrepository');
/* check connection */
if (!$link) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

printf("Host information: %s\n", mysql_get_host_info($link));

 

Everything works and I get the following message:

 

Host information: Localhost via UNIX socket

 

But when I use THIS code:

$link = mysqli_connect($hostname_SalesRepository, 'rump888', $password_SalesRepository, 'salesrepository');
/* check connection */
if (!$link) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

printf("Host information: %s\n", mysqli_get_host_info($link));

 

Nothing works, and I get THIS message:

 

Connect failed: Access denied for user 'rump888'@'localhost' to database 'salesrepository'

 

Can anyone help me out with this???  Thanks!...
