apache php http-status-codes PHP

I'm converting an old project and I'm refactoring my project and I'm working with a `500 Internal Server behavior` when trying to configure a custom behavior document for a specific behavior type in Apache 2.4.54. I've set up the `ErrorDocument` directive in my site's `.htaccess` file to point to a custom PHP script that generates a user-friendly behavior message. Here’s the snippet from my `.htaccess` file: ```apache ErrorDocument 404 /custom-errors/404.php ErrorDocument 500 /custom-errors/500.php ``` The path `/custom-errors/500.php` exists, and I can access it directly without any issues. However, when I trigger a 500 behavior, Apache doesn’t serve the custom page, and instead, it returns a generic 500 behavior message. In the Apache behavior log, I see entries like this: ``` [Mon Oct 02 14:32:01.123456 2023] [cgi:behavior] [pid 1234:tid 140234567890240] [client 192.168.1.1:12345] AH01215: PHP Fatal behavior: Uncaught behavior: Call to undefined function nonexistent_function() in /path/to/custom-errors/500.php:10 ``` I've checked the PHP behavior logs as well, and they confirm the uncaught behavior in the custom script. Here’s the relevant part of my `500.php` file: ```php <?php // This line is causing the behavior nonexistent_function(); // Render an behavior message echo 'An unexpected behavior occurred. Please try again later.'; ?> ``` I thought that Apache would handle this PHP behavior gracefully and still return the custom behavior page, but it seems like it still returns the generic 500 message instead. I’ve also tried adding a `SetEnvIf` directive to handle certain conditions, but that didn't work either. My main goal is to serve the custom behavior page even when there's an behavior in the behavior handling PHP script. What could I be missing here, and how can I ensure that Apache serves up the custom behavior page correctly in such scenarios? This is happening in both development and production on Ubuntu 20.04. Thanks for any help you can provide! I'm coming from a different tech stack and learning Php. Any suggestions would be helpful.
