New Comment:
I am using PHP 5.2.6 with MySQL 5.0.51b, and the problem is still
present.
Reproduce code:
---------------
$sql = "SELECT FileData FROM UserFile WHERE ID=?";
$stmt = $DB->prepare($sql);
$stmt->execute(array($FileID));
$stmt->bindColumn(1, $data, PDO::PARAM_LOB);
$stmt->fetch(PDO::FETCH_BOUND);
echo gettype($data);
Expected result:
----------------
resource
Actual result:
--------------
string

I believe this is probably the same issue, but I also notice that using
MySQL to simply execute a SQL query which contains BLOB result columns
is also returning strings instead of streams. The difference being that
I'm not using bindColumn() and specifying PDO::PARAM_LOB. I wouldn't
expect that I'd need to, since simply performing a standard fetch()
works as expected w/ Postgres (and, I believe, Oracle).

Description:
------------
PDOStatement::bindColumn($idx, $var, PDO::PARAM_LOB) for SELECT query
makes $var a string with the BLOB Data rather than a stream, for both
MySQL and SQLite.
Reproduce code:
---------------
$id = (int)$_REQUEST['book'];
$stmt = $conn->prepare("SELECT coverMime, coverImage FROM books WHERE
id=$id");
$stmt->execute();
$stmt->bindColumn(1, $mime);
$stmt->bindColumn(2, $image, PDO::PARAM_LOB);
$stmt->fetch(PDO::FETCH_BOUND);
var_dump($image);
Expected result:
----------------
Resource #1
Actual result:
--------------
String(792) {GIF89a...}
