advanced patterns with PHP 8.1 and PDO prepared statements when using named placeholders
I'm stuck trying to I'm working on a personal project and Quick question that's been bugging me - I'm working with unexpected behavior when using PDO prepared statements with named placeholders in PHP 8.1..... Specifically, when I prepare a statement with named placeholders and bind values later, it seems that the values are not being bound correctly, leading to SQL errors. Here’s the part of the code where I'm having trouble: ```php $pdo = new PDO('mysql:host=localhost;dbname=testdb', 'user', 'password'); $sql = 'SELECT * FROM users WHERE id = :id'; $stmt = $pdo->prepare($sql); $stmt->execute([':id' => 1]); $result = $stmt->fetch(PDO::FETCH_ASSOC); ``` When I run this code, it throws the following behavior: ``` SQLSTATE[HY093]: Invalid parameter number: parameter was not defined ``` To troubleshoot, I've tried removing the binding array from the `execute()` call and instead using `bindParam()`: ```php $id = 1; $stmt->bindParam(':id', $id); $stmt->execute(); ``` This approach works, but I prefer the original method for clarity. I've also checked that the PDO extension is correctly enabled and that my database connection is working fine. I suspect there might be some configuration or compatibility scenario with PHP 8.1. Is there something specific to this version that could be causing this question, or am I missing something in my approach? Any guidance would be appreciated! My development environment is Linux. This is part of a larger web app I'm building. For context: I'm using Php on CentOS.
