1. I have a database with "utf8_general_ci" as collation.
2. The database contains some data in Arabic Language.
3. The HTML encoding is "UTF-8".
4. When I tried to retrieve the data in HTML, it appears as "?????".

Please Help !!!

回答1:

you must set charset in first connect with mysql by this query:

SET CHARACTER SET utf8

for example in mysqli functions

$MySQL_Handle = mysqli_connect(HOSTNAME,DATABASE_USERNAME,DATABASE_PASSWORD,DATABASE_NAME) 
or die ( mysqli_error($MySQL_Handle) ); 

$sSQL= 'SET CHARACTER SET utf8'; 

mysqli_query($MySQL_Handle,$sSQL) 
or die ('Can\'t charset in DataBase'); 

and PDO sample :

$dbh = new PDO('mysql:host=localhost;dbname=' . $DB_NAME, $DB_USER,
$DB_PASS, array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'UTF8'"));
$dbh->exec("SET CHARACTER SET UTF8");

this action need before insert and before select.
