implementing PHP 8.1 and PDO prepared statements returning empty result sets
I'm working on a personal project and I'm working on a project and hit a roadblock... I'm working with a question with PDO prepared statements in PHP 8.1 where I'm getting empty result sets even though I'm certain the query should return data. I'm using a MySQL database and have verified that the data exists. Here's a simplified version of my code: ```php try { $pdo = new PDO('mysql:host=localhost;dbname=testdb', 'username', 'password'); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt = $pdo->prepare('SELECT * FROM users WHERE age > :age'); $stmt->bindParam(':age', $age); $age = 18; $stmt->execute(); $results = $stmt->fetchAll(PDO::FETCH_ASSOC); if (empty($results)) { echo 'No results found.'; } else { print_r($results); } } catch (PDOException $e) { echo 'Query behavior: ' . $e->getMessage(); } ``` I have confirmed that users older than 18 exist in the `users` table. To troubleshoot, I tried outputting the raw SQL and executing it directly in a MySQL client, which returns the expected rows. I've also checked for issues with the database connection and ensured that my PDO attributes are set correctly but still hit a wall here. Any insights on what might be causing the empty result set would be greatly appreciated! My development environment is Ubuntu. Any help would be greatly appreciated!
