How to display $arrVALUES on the screen?

Question

1C-Bitrix

There is a function in init.php:

function onBeforeResultAddHandler($WEB_FORM_ID, &$arFields, &$arrVALUES) {
...
}

It works with the $arrVALUES array. I want to see what this array is filled with. How can I do this, given that the function is called before the web form data is written. And the page is refreshed by ajax?

I tried:

print_r($arrVALUES);
return;

But of course it doesn't work =)

Answer 1

Throw an exception

$APPLICATION->ThrowException('<pre>' . print_r($arrVALUES, true) . '</pre>');

Well, or pledge data to a file\storage :)
