AFAIK all this conversion stuff is core not driver stuff.

How would one support something for which there is not even any documentation... Apart from that it
just works fine for me...
$db = new PDO( "mysql:host=127.0.0.1;port=3311;dbname=test", "root",
"",
array( PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_EMULATE_PREPARES => false,
PDO::ATTR_STRINGIFY_FETCHES => true,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC ) );
$stmt = $db->query("SELECT 1, 1.23");
var_dump($stmt->fetchAll());
$db->setAttribute(PDO::ATTR_STRINGIFY_FETCHES, false);
$stmt = $db->query("SELECT 1, 1.23");
var_dump($stmt->fetchAll());
array(1) {
[0]=>
array(2) {
[1]=>
string(1) "1"
["1.23"]=>
string(4) "1.23"
}
}
array(1) {
[0]=>
array(2) {
[1]=>
int(1)
["1.23"]=>
string(4) "1.23"
}
}
Please, provide a proper case that can be reproduced. Fetching results from an unknown table
'test' cannot be reproduced and verified.

Description:
------------
When the mysqlnd driver is used PDOStatement->fetchAll(PDO::FETCH_COLUMN |
PDO::FETCH_UNIQUE, 0) does not return proper results when
PDO::ATTR_STRINGIFY_FETCHES and PDO::ATTR_EMULATE_PREPARES set to 0
Test script:
---------------
$pdo = new PDO('mysql:host=127.0.0.1;dbname=test', 'root', '123');
$pdo->setAttribute(PDO::ATTR_STRINGIFY_FETCHES, 0);
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, 0);
var_dump($pdo->query("SELECT id FROM test")->fetchAll(PDO::FETCH_COLUMN |
PDO::FETCH_UNIQUE, 0));
Expected result:
----------------
array(2) {
[1]=>
int(1)
[2]=>
int(2)
}
Actual result:
--------------
array(1) {
[""]=>
int(2)
}
