Getting 'Undefined index' scenarios while accessing nested array with PHP 8.1 and Symfony 5
I'm following best practices but After trying multiple solutions online, I still can't figure this out. I need help solving Can someone help me understand I'm working with an 'Undefined index' behavior when trying to access a nested array in my Symfony 5 application using PHP 8.1. The scenario arises specifically when fetching user data from an API response, which I then process to display in my view. Here's the relevant snippet of code: ```php $response = $client->request('GET', 'https://api.example.com/users/1'); $userData = $response->toArray(); // Assuming userData structure is { 'data': { 'attributes': { 'name': 'John', 'email': 'john@example.com' } } } $userName = $userData['data']['attributes']['name']; ``` The behavior occurs at the line where I'm trying to access the `name`. When I `var_dump($userData)`, I can see that `data` and `attributes` are indeed present, but it seems like the structure is slightly different than expected in some cases, leading to the behavior. I've tried using `isset()` to check for the indexes before accessing them, like this: ```php if (isset($userData['data']['attributes']['name'])) { $userName = $userData['data']['attributes']['name']; } else { $userName = 'Unknown'; // Fallback value } ``` While this prevents the behavior, it doesn't resolve my scenario of understanding why the structure changes. I've also added logging to capture the full API response whenever the behavior occurs, but the `userData` structure seems inconsistent. I suspect there may be some condition in the API response that I'm not handling correctly. Any insights on how to better handle this scenario or debug the varying structure of the API response would be greatly appreciated. This is happening in both development and production on Windows 10. Is there a better approach? For context: I'm using Php on macOS. Any ideas how to fix this? The project is a mobile app built with Php. Any ideas what could be causing this?
