Php displays garbled characters after obtaining mysql Chinese characters. Can you modify it ;? Phpheader ("Content-type: & nbsp; text/html; & nbsp; charset = utf-8"); $ dsn & nbsp ;=& nbsp; 'MySQL: host = localhost; dbname = pw9'; $ db & nbsp; = php displays garbled characters after obtaining mysql Chinese characters. Can you modify it?
header("Content-type: text/html; charset=utf-8");
$dsn = 'mysql:host=localhost;dbname=pw9';
$db = new PDO($dsn,'root','');
$rs = $db->query('SELECT * FROM pw_bbs_threads');
while($row=$rs->fetch()){
print_r($row);
}
1. file encoding: utf8
2. mysql code utf8
3. the browser code utf8
I searched a lot and found that someone said they would like to set names utf8, but I don't know how to write it in this code. please modify it. thank you for sharing it:
------ Solution --------------------
$ Db-> query ("set names utf8 ");
------ Solution --------------------
This is better written.
$ Db = new PDO ($ dsn, 'root', '', array (PDO: MYSQL_ATTR_INIT_COMMAND =>" set names utf8 "));
You won't forget to write $ db-> query ("set names utf8 ");
------ Solution --------------------
Is there a manual?
