implementing JSON Encoding of Multidimensional Arrays in PHP 8.2
I need help solving I recently switched to I'm working with an scenario with JSON encoding of a multidimensional array in PHP 8.2. I have a nested array that I want to convert to a JSON string, but the `json_encode()` function seems to be outputting unexpected results. Here's the code I'm using: ```php $data = [ 'user' => [ 'id' => 1, 'name' => 'John Doe', 'posts' => [ ['title' => 'First Post', 'content' => 'This is my first post!'], ['title' => 'Second Post', 'content' => 'This is my second post!'] ] ] ]; $json = json_encode($data, JSON_PRETTY_PRINT); if (json_last_error() !== JSON_ERROR_NONE) { echo 'JSON behavior: ' . json_last_error_msg(); } else { echo $json; } ``` When I run the above code, the output is as expected, but when I try to add a new post with special characters to the 'content' field, like so: ```php $data['user']['posts'][] = ['title' => 'Third Post', 'content' => 'This is a post with special characters: ñ, ü, and 😊!']; ``` I receive this behavior: `JSON behavior: Malformed UTF-8 characters, possibly incorrectly encoded`. I've verified that the source data is in UTF-8, and I'm not sure what might be causing this scenario. I've tried using `mb_convert_encoding()` on the 'content' string before encoding, but it hasn't resolved the scenario. Anyone have insights on how to handle this correctly or what might be going wrong? I'm coming from a different tech stack and learning Php. Has anyone else encountered this? Thanks for any help you can provide!
