php pdo prepared-statements database PHP

I'm dealing with Could someone explain I'm testing a new approach and I'm sure I'm missing something obvious here, but I'm experiencing an scenario with PDO prepared statements in PHP 8.1 where the bound parameters are not being recognized correctly, resulting in empty result sets....... I've set up a simple query that should fetch user details based on an ID, but when I execute the statement, it returns no rows. Here's the code I'm using: ```php try { $pdo = new PDO('mysql:host=localhost;dbname=testdb', 'user', 'password'); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt = $pdo->prepare('SELECT * FROM users WHERE id = :id'); $userId = 1; $stmt->bindParam(':id', $userId, PDO::PARAM_INT); $stmt->execute(); $result = $stmt->fetchAll(PDO::FETCH_ASSOC); if (empty($result)) { echo 'No user found.'; } else { print_r($result); } } catch (PDOException $e) { echo 'Database behavior: ' . $e->getMessage(); } ``` Despite having a user with ID 1 in the database, the output is always 'No user found.' I've confirmed that the database connection is working and that the table `users` exists with data. I also tried using `bindValue` instead of `bindParam`, but the scenario continues. Is there something specific to PHP 8.1 or PDO that might be causing this unexpected behavior? I am also using MySQL 8.0.23, and I've checked that the user has the necessary permissions. Any help would be greatly appreciated! This is part of a larger web app I'm building. Thanks in advance! My development environment is macOS. Thanks in advance! I'm working with Php in a Docker container on macOS. Is there a simpler solution I'm overlooking? This is happening in both development and production on Windows 10. Thanks for any help you can provide!
