Unexpected Results When Filtering Nested Arrays in Laravel with Collection Methods
I'm following best practices but I'm having a hard time understanding Hey everyone, I'm running into an issue that's driving me crazy. I'm refactoring my project and I'm trying to filter a nested array of user data in Laravel 9 using the Collection methods... The structure of the data is a bit complex, and I'm running into unexpected results when trying to use the `filter` method. Here's a snippet of the data I'm working with: ```php $users = [ ['id' => 1, 'name' => 'Alice', 'courses' => [ ['course_id' => 101, 'completed' => true], ['course_id' => 102, 'completed' => false] ]], ['id' => 2, 'name' => 'Bob', 'courses' => [ ['course_id' => 101, 'completed' => false], ['course_id' => 103, 'completed' => true] ]], ['id' => 3, 'name' => 'Charlie', 'courses' => [ ['course_id' => 102, 'completed' => true] ]] ]; ``` I want to filter this array to get users who have completed at least one course. I've tried using the `filter` method like this: ```php $completedUsers = collect($users)->filter(function ($user) { return collect($user['courses'])->contains('completed', true); }); ``` However, the `$completedUsers` collection ends up being empty, which isn't what I expected. I printed out some debug information and confirmed that there are indeed users who have completed courses. I even tried to isolate and test the inner collection: ```php $test = collect($users[0]['courses'])->contains('completed', true); // returns true ``` I've also tried using the `map` method before filtering, but that seems to complicate things unnecessarily. What am I missing here? Is there a better way to achieve this filtering? Any insights or suggestions would be greatly appreciated! Am I approaching this the right way? I've been using Php for about a year now. I'd be grateful for any help. This is happening in both development and production on Windows 11. Could this be a known issue? I'm open to any suggestions.
