php symfony pdo

I'm working through a tutorial and I'm integrating two systems and I'm having trouble with I'm upgrading from an older version and I'm working with an scenario while trying to serialize a PDO statement object in my Symfony 5.2 application running on PHP 8.1... When I attempt to pass the statement object to a session for later use, I receive the behavior: `Serialization of 'PDOStatement' is not allowed`. I understand that PDOStatement objects want to be serialized directly, but I thought I could save the necessary parameters and re-instantiate the statement later. Here's what I tried: ```php // Retrieving the statement $stmt = $this->entityManager->getConnection()->prepare('SELECT * FROM users WHERE id = :id'); $stmt->bindValue(':id', 1); $stmt->execute(); // Attempting to serialize the statement $serializedStmt = serialize($stmt); ``` I also tried extracting the SQL query and parameters manually: ```php $query = $stmt->queryString; $params = $stmt->getBindValues(); ``` However, once I get the parameters, I’m unsure how to structure the re-instantiation later. When I do the following: ```php $recreatedStmt = $this->entityManager->getConnection()->prepare($query); foreach ($params as $key => $value) { $recreatedStmt->bindValue($key, $value); } $recreatedStmt->execute(); ``` It does not return the same result set. I suspect it's due to the way I'm handling the parameter binding or because the original PDOStatement holds some state that I'm missing. How can I correctly serialize the necessary information from the PDO statement and recreate it later without losing its context? I'm working on a web app that needs to handle this. Any ideas what could be causing this? Thanks in advance! I'm working on a microservice that needs to handle this. This is my first time working with Php 3.11. Could this be a known issue? Any help would be greatly appreciated! Thanks, I really appreciate it!
