PHP to get MySQL after Chinese display garbled, can help to modify it?

 
  Query (' SELECT * from Pw_bbs_threads '), while ($row = $rs->fetch ()) {Print_r ($row);}

1. File Encoding UTF8
2.mysql encoded UTF8
3. Browser Encoding UTF8

Search a lot, found that someone said to set names UTF8, but in my this code do not know how to write, Trouble Gao modified thank you

Reply to discussion (solution)

$db->query ("SET NAMES UTF8");

$db->query ("SET NAMES UTF8");
What's the sentence behind this sentence?

$db->query ("SET NAMES UTF8");
OK
But a little confused, in the PHP manual

Pdostatement pdo::query (String $statement) pdostatement pdo::query (string $statement, int $PDO:: fetch_column, int $c Olno) pdostatement pdo::query (string $statement, int $PDO:: Fetch_class, String $classname, array $ctorargs) Pdostatem Ent pdo::query (string $statement, int $PDO:: Fetch_into, Object $object)

The parameter inside is the first argument string $statement?

That is true..

It's better to write like this
$db = new PDO ($dsn, ' root ', ' ', array (Pdo::mysql_attr_init_command = "Set Names UTF8"));
Do not forget to write $db->query ("SET NAMES UTF8"); and the problem

It's better to write like this
$db = new PDO ($dsn, ' root ', ' ', array (Pdo::mysql_attr_init_command = "Set Names UTF8"));
Do not forget to write $db->query ("SET NAMES UTF8"); and the problem
Thank you very much, the line of the pass, in addition to consult, I consulted php.net PDO class, only the class summary information (inside the class method, but there is no class of static variables, such as Pdo::mysql_attr_init_command why I can't find it on top, Where can you see it?

It's not in the manual, is it?
