PHP 8.1: guide with PDO Prepared Statements Not Binding Parameters Correctly in MySQL
After trying multiple solutions online, I still can't figure this out. I've been banging my head against this for hours. I'm working on a personal project and This might be a silly question, but I'm experiencing an scenario with PDO prepared statements in PHP 8.1 where the parameters don't seem to bind correctly to the SQL query... I have a simple `User` class that interacts with a MySQL database using PDO. The method `getUserById` should retrieve a user record based on the provided user ID. However, when I execute the query, it returns an empty result set even though the user ID exists in the database. Here's the relevant code snippet: ```php class User { private $pdo; public function __construct($pdo) { $this->pdo = $pdo; } public function getUserById($id) { $stmt = $this->pdo->prepare('SELECT * FROM users WHERE id = :id'); $stmt->bindParam(':id', $id, PDO::PARAM_INT); $stmt->execute(); return $stmt->fetch(PDO::FETCH_ASSOC); } } ``` In my code, I'm calling the method like this: ```php $userModel = new User($pdo); $user = $userModel->getUserById(1); ``` However, when I check the value of `$user`, it returns `false` instead of the expected user data. I've also verified that the user with ID `1` exists in the database. I’ve tried different binding methods as well, but the result remains the same. When I manually run the SQL query in MySQL Workbench, it returns the correct record. I also checked for any potential issues with the PDO connection settings and confirmed that behavior reporting is enabled, yet no exceptions are being thrown. Is there something I'm overlooking with parameter binding or any common pitfalls with PDO in PHP 8.1? Any insights would be appreciated. Is there a better approach? This is part of a larger application I'm building. Is there a better approach? I'm coming from a different tech stack and learning Php.
