Unexpected `foreach` behavior when modifying an array during iteration in PHP 8.1
I'm trying to configure Hey everyone, I'm running into an issue that's driving me crazy... I'm working with an scenario with modifying an array while iterating over it using `foreach` in PHP 8.1. When I try to unset elements from the array during the iteration, it seems to skip some elements or, worse, throw unexpected behavior. Here's a simplified version of my code: ```php $array = [1, 2, 3, 4, 5]; foreach ($array as $key => $value) { if ($value % 2 == 0) { unset($array[$key]); } } print_r($array); ``` In this example, I expected the output to be `[1, 3, 5]`, but instead, I ended up with an array that contains `1, 3, 4, 5`. This behavior is confusing because modifying the array should ideally not affect the current iteration context. I've also tried using a separate array to collect the values to keep, but that feels less efficient. I understand that directly modifying the array while iterating over it can lead to unexpected results, but in this case, it seems especially problematic. Is there a more effective way to handle this situation without running into these issues? Any insights on best practices for safely modifying arrays during iteration would be greatly appreciated! Any ideas how to fix this? Thanks in advance! I'm working in a Ubuntu 22.04 environment. I'd love to hear your thoughts on this.
