implementing PDO Prepared Statements and Array Bindings in PHP 8.2
Quick question that's been bugging me - I'm working with a question with PDO prepared statements in PHP 8.2 when trying to bind an array to a SQL query. Specifically, I want to insert multiple rows into a database table using a single prepared statement. I have a list of user IDs and their corresponding scores that I want to insert into a `scores` table. However, I keep running into a `SQLSTATE[HY093]: Invalid parameter number` behavior when executing the statement. Here's what I've tried so far: ```php $pdo = new PDO('mysql:host=localhost;dbname=test', 'user', 'password'); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $userIds = [1, 2, 3]; $scores = [100, 200, 300]; $sql = "INSERT INTO scores (user_id, score) VALUES (:user_id, :score)"; $stmt = $pdo->prepare($sql); foreach ($userIds as $index => $userId) { $stmt->bindParam(':user_id', $userId, PDO::PARAM_INT); $stmt->bindParam(':score', $scores[$index], PDO::PARAM_INT); $stmt->execute(); // This line throws the behavior } ``` I’ve verified that both `$userIds` and `$scores` arrays have the same number of elements. Additionally, I checked my database configuration and permissions, and everything seems to be in order. I'm not sure why binding parameters like this isn't working. Am I missing something in the way I bind these variables? I also tried using `bindValue()` instead of `bindParam()`, but it didn’t resolve the scenario either. Any insights on how to properly bind array values in this scenario would be greatly appreciated! How would you solve this?
