laravel-ignition VS Whoops

Check out spatie/laravel-ignition (if using Laravel) or filp/whoops

I haven't worked on this myself, but several of my colleagues did. Ignition has been the default error handler in Laravel for a while now, and the newest release now allows any PHP to use it. All Laravel-specific features are separated in spatie/laravel-ignition now.

To get the full control of the error output (or, rather, of the error message handling) I would suggest to use an exception handling function, set_exception_handler() I've got an example in my article on PHP error reporting. There, instead of just spitting out the raw exception, you can use the Exception class methods to get the relevant parts and either log or echo them out, depends on the server role. Or you can even include a library like Whoops that dramatically improves the output.

I've been using whoops but it's a bit stale (not even 7.x or 8.x native, just compatible with those but still very much 5.x code). Might have to explore ignition.

To give an example of what I am looking for, there is this library for PHPT: http://filp.github.io/whoops/

You're correct about it being a faulty webpage, but that's now what any browsers devtools look like. What you're seeing here is a whoops error page from an older version of Laravel.
