PHP 8.0 PDO Prepared Statement scenarios to Bind Values When Using Named Placeholders in Loop
Could someone explain I've searched everywhere and can't find a clear answer. I'm running into a frustrating scenario with PHP 8.0 and PDO prepared statements. I have a script where I'm trying to insert multiple rows into a database table using named placeholders in a loop. However, only the first row is being inserted, and I get a warning saying `PDOException: SQLSTATE[HY093]: Invalid parameter number: parameter was not defined`. Here's the part of the code where the scenario occurs: ```php $dsn = 'mysql:host=localhost;dbname=testdb;charset=utf8mb4'; $username = 'root'; $password = ''; try { $pdo = new PDO($dsn, $username, $password); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { echo 'Connection failed: ' . $e->getMessage(); } $data = [ ['name' => 'Alice', 'age' => 30], ['name' => 'Bob', 'age' => 25], ['name' => 'Charlie', 'age' => 35], ]; $sql = 'INSERT INTO users (name, age) VALUES (:name, :age)'; $stmt = $pdo->prepare($sql); foreach ($data as $user) { // This line is causing the question $stmt->bindParam(':name', $user['name']); $stmt->bindParam(':age', $user['age']); $stmt->execute(); } ``` I've tried using `bindValue` instead of `bindParam`, but that didn't help either. I also checked that the database connection is working fine and that the `users` table exists with the appropriate columns. Any idea why the binding fails after the first iteration? Should I be using a different approach to bind parameters in a loop like this? Any ideas what could be causing this? Thanks for taking the time to read this!
