PHP - Joomla Custom Component Development

I'm sure it's not much, but I'm not understanding something with custom error handlers:

I've created a custom error handler, which I initially set when my page loads :

set_error_handler(array ( new ErrorHandler(), 'handleError' ));

It seems to catch all internal PHP errors, such as if I: var_dump($non_existing_var); right after the set_error_handler....

Now, I have an object that throws an exception after:

set_error_handler(array ( new ErrorHandler(), 'handleError' )); 
$locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception 
...

I thought that with an error handler set, I could 'skip' the try/catch for it, but doing so, PHP spits out in its internal log:

PHP Fatal error: Uncaught CorbeauPerdu\i18n\LocaleException: ....

My error handler doesn't catch it at all before, thus my page breaks!!

If I want it to go through the error handler, I have to init my Locale with a try/catch and use trigger_error() like so:

set_error_handler(array ( new ErrorHandler(), 'handleError' ));

try { 
  $locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception 
}
catch(Exception $e) { 
  trigger_error($e->getMessage(), E_USER_ERROR); 
} 
...

Is this normal ? I thought one of the goals of the error_handler was to catch anything that wasn't dealt with?

Thanks for your answers!

Hi all.

Does anyone use Localstack to for local AWS development? I'm currently developing on a system that uses numerous AWS SQS queues, AWS ElasticSearch, AWS Redis, and many, many S3 buckets with about three dozen PHP-based micro-services; I've built a local development environment consisting of containers using several Docker images, one of which mocks AWS using a Localstack image. This works, for the most part, but I find that the Localstack instance just ... stops working. It - after a random amount of time, and intermittently if more often than not - won't process any of the queues that the system uses, or will drop bucket contents despite being set up for persistence (the `DATA_DIR` objective is set to `/tmp/localstack/data` as instructed in the README).

I get the impression that Localstack is fairly widely used for local AWS development, so I have to assume if this was a normal situation I'd've found it in my searching, but so far it doesn't seem to be a big deal. I'll post the docker-compose file here if it helps, but does anyone have any experience with a similar situation and feel like sharing tips? Did it work, did it not, do I need to convince my company to pay for the pro version, do I need to do a modified rain dance, etc?

As always, thanks in advance for any thoughts or advice.

Chrome? Edge? Other? Had a bad experience with Edge.

If development tools make one better than the other - what tools?

And if you are using PHPStorm maybe the choice of browser is less important? No?
