Question

when initializing PDO - should I do: charset=UTF8 or charset=UTF8MB4 ?

here\'s my intialization:

            $dsn = \'mysql:host=example.com;dbname=t         


        

Answer 1

You should use utf8mb4 for PDO and your database structures.

$dsn='mysql:host=example.com;dbname=testdb;port=3306;charset=utf8mb4';

When possible, don't forget to set the character encoding of your pages as well. PHP example:

mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
