advanced patterns with `count()` and `array_filter()` on Multidimensional Arrays in PHP 8.2
I'm stuck trying to I'm working on a project and hit a roadblock. I can't seem to get I'm trying to implement I'm working with a puzzling scenario while trying to count filtered items in a multidimensional array in PHP 8.2. I have a nested array of products, each with various attributes, and I'm trying to filter this array based on a specific condition and count the results. Here's the code snippet I'm currently using: ```php $products = [ ['name' => 'Product A', 'price' => 20, 'available' => true], ['name' => 'Product B', 'price' => 30, 'available' => false], ['name' => 'Product C', 'price' => 25, 'available' => true], ]; $availableProducts = array_filter($products, function($product) { return $product['available'] === true; }); $count = count($availableProducts); ``` After executing this, I expected `$count` to yield `2`, but it returns `0`. I've verified that the `array_filter()` is indeed returning an array, but when I check its contents with `var_dump($availableProducts)`, it shows that it's empty. I suspect there might be an scenario with how I'm evaluating the condition or with the structure of the array itself. I've also tried modifying the filter callback to use strict comparison, but it still results in an empty array. The behavior continues regardless of how I structure the filter condition, leading me to think there might be something deeper happening with type coercion or array structure in PHP 8.2. Does anyone have insights into why `count()` returns `0` in this scenario? What could I be overlooking in my implementation? Any help would be appreciated! This is happening in both development and production on Linux. What am I doing wrong? I'd really appreciate any guidance on this. I'm working with Php in a Docker container on CentOS. What's the best practice here? The project is a web app built with Php. Am I missing something obvious?
