Hi @mrhussnain , thanks for the reply.
Tried that too… same result. Did you try this out too? Had any success?
here my code, error was (Error! :: SQLSTATE[HY000] [2054] Server sent charset unknown to the client. Please, report to the developers)

2 tests (one with PDO other with mysql_connect)

$link = mysqlconnect(’**:’, ’**’, ’***’);
mysqlsetcharset(‘utf8mb4’,$link);
if (!$link) {
// die('Could not connect utf8mb4: ’ . mysqlerror());
echo 'Connected unsuccessfully::’. mysql_error();
}

echo 'Connected successfully’;

try {
    $DB_HOST = '****';
    $DB_PORT = '***';
    $DB_USER = '***';
    $DB_PASS = '*****';
    $DATABASE = '*****';

    $dsn = 'mysql:';
    $dsn .= 'host=' . $DB_HOST . ';';
    $dsn .= 'port=' . $DB_PORT . ';';
    //if (!empty($this->DBName)) {
    $dsn .= 'dbname=' . $DATABASE . ';';
    //}
    $dsn .= 'charset=utf8mb4;';
    $dbh = new PDO($dsn,
    $DB_USER,
    $DB_PASS
    );
} catch (PDOException $e) {
    print "Error! :: " . $e->getMessage() . "<br/>";
    die();
}
