How to apply bindValue method in LIMIT clause?

I remember having this problem before. Cast the value to an integer before passing it to the bind function. I think this solves it.

$fetchPictures->bindValue(':skip', (int) trim($_GET['skip']), PDO::PARAM_INT);

The simplest solution would be to switch the emulation mode off. You can do it by simply adding the following line

$PDO->setAttribute( PDO::ATTR_EMULATE_PREPARES, false );

Also, this mode can be set as a constructor parameter when creating a PDO connection. It could be a better solution as some report their driver doesn't support the setAttribute() function.

It will not only solve your problem with binding, but also let you send values directly into execute(), which will make your code dramatically shorter. Assuming the emulation mode has been already set, the whole affair will take as much as half a dozen lines of code

$skip = isset($_GET['skip']) ? (int)trim($_GET['skip']) : 0;$sql  = "SELECT * FROM pictures WHERE album = ? ORDER BY id LIMIT ?, ?";$stmt  = $PDO->prepare($sql);$stmt->execute([$_GET['albumid'], $skip, $max]);$pictures = $stmt->fetchAll(PDO::FETCH_ASSOC);

Looking at the bug report, the following might work:

$fetchPictures->bindValue(':albumId', (int)$_GET['albumid'], PDO::PARAM_INT);$fetchPictures->bindValue(':skip', (int)trim($_GET['skip']), PDO::PARAM_INT);  

but are you sure your incoming data is correct? Because in the error message, there seems to be only one quote after the number (as opposed to the whole number being enclosed in quotes). This could also be an error with your incoming data. Can you do a print_r($_GET); to find out?
