使用PHP将希腊语/土耳其语/波兰语字母插入mysql数据库时遇到问题

Question

I'm reading the word Αθήνα from a table which is utf8_unicode_ci encoded and can display it without problem on a utf-8 HTML page. i scrape some more greek and also this is shown correctly. now i want to write the information back to the database in another utf8 table. but the results are this: ????? or Î?θήνα(when i use utf8_encode() on it). I also set

$this -> mysqli->set_charset("utf8");

What am I doing wrong, this is driving me crazy? Any help appreciated thx a lot!

its basically

read out:

    $result = $this -> mysqli->query("SELECT * FROM `A` WHERE `country_code` = 'GRC'");
    /* Tell browser to use UTF-8 */
    header("Content-Type: text/html; charset=utf-8");
    /* The actual scrape loop, done for every found entry in the urls table*/
    while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
       $this -> urls_array[] = $row;
    }

write back:

$deal=$this -> urls_array[$key];
$this -> mysqli->query("INSERT INTO `B` (`city_name`,`title`....) 
        VALUES (
            '{$deal["city_name"]}',
            '{$title}'
            )
            ");

Try executing "SET NAMES utf8" before inserting anything. There's a modern way of doing it but nonetheless this should work.
