How to Resolve PDO bindValue Syntax Errors in LIMIT Clauses?

Resolving Syntax Error in LIMIT Clause with bindValue Method

Facing an error while using the bindValue method in conjunction with the LIMIT clause? It's likely due to the addition of single quotes by PDO to numerical parameters. This issue has been reported (PHP Bug #44639) and suggests that casting the values to integers before using bindValue can alleviate the problem.

To apply the bindValue method in the LIMIT clause effectively, follow these steps:

  1. Ensure the variables you're using in the LIMIT clause are numerical (integers).
  2. When using bindValue to assign these variables, cast them to integers first using the (int) type casting operator.

e.g., Replace:

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

With:

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

By following this method, you can avoid the addition of single quotes and resolve the syntax error in your LIMIT clause.
