Unexpected behavior with PHP 8.0's array_column and null values
I've looked through the documentation and I'm still confused about I'm updating my dependencies and I'm encountering an issue with PHP 8.0 when using the `array_column` function... I have an array of associative arrays where some entries may have a key that is set to `null`. I expected `array_column` to handle this situation gracefully, but instead, I'm getting unexpected results. Here's the array I'm working with: ```php $data = [ ['id' => 1, 'name' => 'Alice'], ['id' => 2, 'name' => 'Bob'], ['id' => 3, 'name' => null], ['id' => 4, 'name' => 'Charlie'], ]; ``` When I run the following code: ```php $names = array_column($data, 'name'); print_r($names); ``` I expected to see an array with all the names including a `null` entry: ``` Array ( [0] => Alice [1] => Bob [2] => [3] => Charlie ) ``` Instead, the output is: ``` Array ( [0] => Alice [1] => Bob [2] => Charlie ) ``` It seems like the entry with the `null` value is being ignored completely. I've checked the documentation and it doesn't explicitly state that `array_column` will skip `null` values. To troubleshoot, I tried adding a conditional check before using `array_column`, like so: ```php $data = array_filter($data, function($item) { return isset($item['name']); }); $names = array_column($data, 'name'); print_r($names); ``` However, this approach changes the indexes of the resulting array and is not what I want. I want to preserve the keys and still capture the `null` values. Is there a way to achieve my desired outcome while keeping the index intact and including `null` values? Any insights or best practices would be greatly appreciated! I recently upgraded to Php stable. What are your experiences with this? I'm working in a CentOS environment. Thanks in advance!
