best practices for 'Array to string conversion' scenarios when using PDO with MySQL in PHP 8.1?
I'm writing unit tests and I'm working with an 'Array to string conversion' behavior when trying to bind parameters in a prepared statement with PDO in PHP 8.1... Here's the scenario: I'm attempting to insert multiple rows into a table and I'm using an associative array for the data. My code looks like this: ```php $data = [ ['name' => 'John', 'email' => 'john@example.com'], ['name' => 'Jane', 'email' => 'jane@example.com'], ]; $db = new PDO('mysql:host=localhost;dbname=testdb', 'user', 'pass'); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt = $db->prepare('INSERT INTO users (name, email) VALUES (:name, :email);'); foreach ($data as $user) { $stmt->bindParam(':name', $user['name']); $stmt->bindParam(':email', $user['email']); $stmt->execute(); } ``` However, I keep getting the behavior message: "PHP Warning: Array to string conversion on line X" at the `bindParam` line where I bind the parameters. I thought that the associative array elements would be correctly passed to the placeholders. I've tried using `bindValue` instead, but the question continues. Is there something wrong with my approach, or do I need to adjust the way I'm handling the data? Any suggestions would be greatly appreciated! I'm working on a API that needs to handle this. My development environment is Linux. What's the best practice here? I've been using Php for about a year now. Any advice would be much appreciated.
