The PDO::MYSQL_ATTR_INIT_COMMAND seem to break down the query, try your own.
The following:
$connection = new \PDO("mysql:host=localhost;dbname=php_orm_test", "dev", "dev",[
PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES UTF8; SET CHARACTER SET UTF8; SET character_set_connection=UTF8; SET character_set_client=UTF8;"
]);
$statement = $connection->prepare("describe users");
$statement->execute();
$statement->fetchAll(\PDO::FETCH_ASSOC);
var_dump($statement->errorInfo());
$statement->closeCursor();
Throws:
array(3) {
[0]=>
string(5) "00000"
[1]=>
int(2014)
[2]=>
string(269) "Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute."
}
If I remove the MYSQL_ATTR_INIT_COMMAND everything works fine instead... any idea?
Notice that not even this does work...
PDO::MYSQL_ATTR_INIT_COMMAND => self::DRIVER_INIT,
PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true

You are using PHP >= 5.3.6, so add charset to dsn and don't use PDO::MYSQL_ATTR_INIT_COMMAND. Further I think you can only execute 1 query with PDO::MYSQL_ATTR_INIT_COMMAND. That might be the problem.
mysql:host=localhost;dbname=php_orm_test;charset=utf8
