PHP 8.2 scenarios When Using array_map with Closures and Class Methods
I need some guidance on I'm trying to figure out I tried several approaches but none seem to work. I've been working on this all day and I'm sure I'm missing something obvious here, but I've looked through the documentation and I'm still confused about I'm working with an scenario with PHP 8.2 when trying to use `array_map` with a closure that calls a method from a class. I have a class `User` with a method `transformData`, and I'm trying to apply it to an array of user data. Here's a simplified version of my code: ```php class User { public function transformData($data) { return strtoupper($data); } } $users = ['alice', 'bob', 'charlie']; $user = new User(); // Attempting to use array_map with a closure $transformedUsers = array_map(function($name) use ($user) { return $user->transformData($name); }, $users); print_r($transformedUsers); ``` Despite the code looking correct, I receive the following warning: ``` Warning: array_map(): Argument #1 ($callback) must be a valid callback, non-static method User::transformData() want to be called statically ``` I’ve tried different approaches to call the method, such as making it static or changing the closure, but I still can’t get it to work. I even checked PHP's documentation, which suggests that this usage should be valid. Is there something specific about closures and class methods in PHP 8.2 that I might be missing? Any insights or workarounds would be appreciated. My development environment is Linux. Is there a better approach? The stack includes Php and several other technologies. I'm working in a Ubuntu 22.04 environment. What would be the recommended way to handle this? Has anyone else encountered this? I appreciate any insights!
