    You cannot (successfully) combine mysqli_*() and mysql_*() functions. I'll let you figure out if it's just a typo, or a deeper problem.

    MySQLi uses mysql_select_db() as a parameter of mysqli_connect()
    PHP Code:
    <?php
    $sql_username 
    'ssstcoin_Sar';
    $sql_password 'password';
    $sql_database ''// need a valid dbname here

    $link mysqli_connect(NULL$sql_username$sql_password$sql_database);
    unset(
    $sql_username$sql_password);

    if ((
    $error mysqli_connect_error())) {
        echo 
    'Failed to connect to MySQL: ' $error;
    }
    echo 
    'Connection to the Server opened';
    mysqli_close($link);
    ?>
