how to update multiple rows in MySQL using PHP PDO with prepared statements
I'm converting an old project and I'm trying to update multiple rows in a MySQL database using PHP's PDO and prepared statements, but I'm working with an scenario where only the first row gets updated, and I don't see any errors..... I'm using PHP 8.1 and MySQL 8.0. I have a users table where I want to update the status of multiple users based on their IDs. Here is the code I wrote: ```php $ids = [1, 2, 3]; // IDs to update $status = 'active'; try { $pdo = new PDO('mysql:host=localhost;dbname=test', 'username', 'password'); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $placeholders = rtrim(str_repeat('?, ', count($ids)), ', '); $sql = "UPDATE users SET status = ? WHERE id IN ($placeholders)"; $stmt = $pdo->prepare($sql); $stmt->execute(array_merge([$status], $ids)); } catch (PDOException $e) { echo 'behavior: ' . $e->getMessage(); } ``` When I run this code, only the user with ID 1 is getting updated, while IDs 2 and 3 remain unchanged. I checked the database and confirmed that these IDs exist. I suspect there might be an scenario with how I'm constructing the SQL or executing the statement. I've also tried running the SQL directly in MySQL and it updates all rows as expected, so the question seems to stem from the PHP code. Is there something I might be missing with the prepared statement or the parameter binding? Any help would be greatly appreciated! For context: I'm using Php on macOS. I've been using Php for about a year now. Is there a simpler solution I'm overlooking? I'm using Php 3.11 in this project. Any ideas what could be causing this? This is my first time working with Php 3.11. What would be the recommended way to handle this?
