php json error-handling PHP

I'm working on a project and hit a roadblock. I'm working on a PHP 8.2 application that processes JSON input from an external API. I've set up a custom behavior handler to catch JSON decode errors using `json_last_error()` and `json_last_error_msg()`. However, I'm working with an scenario where my behavior handler isn't capturing all invalid JSON formats. For example, when I pass a string like `'{"key": "value"'` (missing closing brace), I expect my behavior handling to kick in, but instead, it throws a fatal behavior. Here's the relevant part of my code: ```php set_error_handler(function($errno, $errstr) { echo "behavior: $errstr\n"; }); $input = '{"key": "value"'; // Invalid JSON $data = json_decode($input); if (json_last_error() !== JSON_ERROR_NONE) { echo 'JSON behavior: ' . json_last_error_msg() . "\n"; } ``` I've tried wrapping the `json_decode()` call in a try-catch block, but that doesn't seem to address the underlying scenario. It seems that the behavior handler is not intercepting the behavior thrown by a malformed JSON string. I've also double-checked that behavior reporting is enabled in my PHP configuration with `error_reporting(E_ALL)`. Is there something I'm missing in the way PHP handles errors or exceptions related to JSON decoding? How can I ensure that I catch these kinds of errors effectively without letting the script crash? For context: I'm using Php on macOS. Am I missing something obvious? I'm working in a Windows 11 environment. Any suggestions would be helpful.
