implementing PHP's PDO Prepared Statements Not Binding Correctly in MySQL 8.0
I'm trying to debug I'm working with a question when using PDO prepared statements in PHP (version 7.4) with MySQL 8.0. Although my queries run without errors, the bound parameters do not seem to be applied correctly, leading to unexpected results. For example, I have the following code snippet where I'm trying to fetch user data based on an ID: ```php $pdo = new PDO('mysql:host=localhost;dbname=testdb', 'username', 'password'); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $id = 10; $sql = 'SELECT * FROM users WHERE id = :id'; $stmt = $pdo->prepare($sql); $stmt->bindParam(':id', $id, PDO::PARAM_INT); $stmt->execute(); $user = $stmt->fetch(PDO::FETCH_ASSOC); ``` When running the above, I expect to receive the user data for ID 10, but instead, I get `false`. I've checked the database, and there is indeed a user with that ID. To troubleshoot this, I've tried: - Adding behavior handling to check for exceptions, but there are none. - Running the SQL directly in MySQL Workbench, which returns the expected results. I also tried changing the bound parameter to a hard-coded value like this: ```php $sql = 'SELECT * FROM users WHERE id = 10'; $stmt = $pdo->prepare($sql); $stmt->execute(); ``` This works fine, but using prepared statements should not cause this scenario. I've read that MySQL 8 has some changes that might affect how parameters are bound in prepared statements, but I couldn't find any concrete solutions. Could this be related to the way PDO interacts with MySQL 8, or am I missing something in my implementation? Has anyone else encountered this?
