GET charset with mysql PDO

Question

Is there a way of retrieving the current character set with PDO? I used to have a little test with Mysqli to check if the forced character set was set by retrieving it like

Answer 1

If we run the following MySQL query;

mysql> SELECT COLLATION('foo');
+-----------------------+
| COLLATION('foo')      |
+-----------------------+
| utf8_general_ci       |
+-----------------------+
1 row in set

So, we can use the following to get the charset

$objCharset = $objPdo->query("SELECT COLLATION('foo')");
echo $objCharset->fetch(PDO::FETCH_NUM)[0]; //Output: utf8_general_ci

• PDO Query
• PDO Fetch
• Cubrid thread

You can then go a step further, and use the following (with object injection).

query("SELECT COLLATION('foo')");
      return $objCharset->fetch(PDO::FETCH_NUM)[0];
   }
}

$objFoo = new foo();
$objPDO = new PDO(...);
echo $objFoo->get_charset($objPDO);
