Using utf8mb4 with php and mysql

Question

I have read that mysql >= 5.5.3 fully supports every possible character if you USE the encoding utf8mb4 for a certain table/column http://mathiasbynens.be/n

Answer 1

This is what i used, and worked good for my problem using euro € sign and conversion for json_encode failure.

php configurations script( api etc..)

header('Content-Type: text/html; charset=utf-8');
ini_set("default_charset", "UTF-8");
mb_internal_encoding("UTF-8");
iconv_set_encoding("internal_encoding", "UTF-8");
iconv_set_encoding("output_encoding", "UTF-8");

mysql tables / or specific columns

utf8mb4

mysql PDO connection

$dsn = 'mysql:host=yourip;dbname=XYZ;charset=utf8mb4';

(...your connection ...)

before execute query (might not be required):

$dbh->exec("set names utf8mb4");
