Handling Recursion Limit in PHP with Large Nested Arrays when Using array_walk()
I'm working on a project and hit a roadblock. I'm experiencing a 'Maximum function nesting level of '100' reached' behavior when trying to process a large nested array using `array_walk()` in PHP 8.0. My array is structured to have multiple levels of nesting, and I'm trying to apply a callback function that modifies each element. Here's the relevant portion of my code: ```php $data = [ 'user' => [ 'name' => 'John', 'contacts' => [ 'email' => 'john@example.com', 'phones' => [ 'home' => '123-456-7890', 'work' => '987-654-3210' ] ] ] ]; function modify(&$value, $key) { if (is_array($value)) { array_walk($value, 'modify'); // Recursive call } else { $value = strtoupper($value); } } array_walk($data, 'modify'); ``` I've also tried increasing the recursion limit with `ini_set('xdebug.max_nesting_level', 200);`, but it doesn't seem to help. I've checked the structure of my array, and it appears to be correct without any circular references. Is there a better way to handle this, or should I consider a different approach to avoid hitting this limit? Any best practices or design patterns for working with deeply nested arrays would be appreciated. What am I doing wrong?
