Finishing with kernel.response and kernel.exception

Oh no! That is weird - the dump() should dump something. If you change this to dump($event);die('test') - do you see the word "test"? Also, check that php.ini is setup to show syntax errors. You can do this by running the following command at the command line:

php -i | grep display_errors

If this says "No" or "Off" or something like that, it could be a problem :). You can fix it by editing your php.ini file and changing this setting. To find where your php.ini file is, use:

php --ini

And look for "Loaded Configuration File".

Let me know what you find out!

Yes, I see "test".

$ php -i | grep display_errors
display_errors => STDOUT => STDOUT

Options in php.ini:

display_errors=On
display_startup_errors=On
error_reporting=E_ALL
html_errors=On
log_errors=On

were commented out before . Recheck for sure I set up values on them(see above), save, and then restart Appache. Nevertheless still empty page.
If I check:

$event = new FilterControllerEvent($this, $controller, $request, $type);
dump($event);die('test2');

That woks fine, I get object:

test2

HttpKernel.php on line 151:
FilterControllerEvent {#107 ▼
-controller: array:2 [▶]
-kernel: HttpKernel {#246 ▶}
-request: Request {#7 ▶}
-requestType: 1
-propagationStopped: false
}

Tell me, Ryan, please, did you try to check:

$event = new GetResponseEvent($this, $request, $type);
dump($event);die;

on your computer?
What did you get in browser ?

Hi Andrew!

You stumbled upon a *really* interesting thing :). In Symfony, the dump() function relies on a listener on kernel.request - called DumpListener - to "initialize" itself. If you try to use dump() before kernel.request is dispatched, it won't work. I honestly never knew that - I had never used dump() this early in the process :).

Cheers!
