php php8 error-handling PHP

I'm dealing with I'm working on a personal project and I'm working on a PHP 8.1 application where I'm using array destructuring to unpack values from an associative array... Recently, I encountered a frustrating `Undefined array key` notice when trying to destructure an array that may not contain all the expected keys. Here's a simplified version of my code: ```php $data = [ 'name' => 'John Doe', 'email' => 'john@example.com', //'age' => 30, // This line is commented out to simulate the missing key ]; // Attempting to destructure the array [ 'name' => $name, 'email' => $email, 'age' => $age, ] = $data; // Output the variables echo "Name: $name\nEmail: $email\nAge: $age\n"; ``` When running this, I get the notice: `PHP Notice: Undefined array key "age"`. I want to avoid this notice without adding explicit checks for each key. I also want to ensure that if a key is missing, the variable defaults to `null` instead of throwing an behavior. I've tried using the null coalescing operator, like this: ```php $age = $data['age'] ?? null; ``` But this approach feels unclean, given that I want to maintain a destructuring style. Is there a more elegant way to handle this situation using PHP's features? Additionally, is there any potential performance impact when using these methods in a loop? Any insights or best practices would be greatly appreciated! My development environment is macOS. Any help would be greatly appreciated! Any ideas what could be causing this? I'm working on a desktop app that needs to handle this. I'd be grateful for any help. I recently upgraded to Php LTS. Could this be a known issue? My team is using Php for this service. I appreciate any insights!
