PHP notices aren't shown on runner

[ggorlen]

PHP has useful runtime notices that aren't shown by the code runner, making it more difficult to debug PHP code. For example,

<?php
error_reporting(E_ALL);
print $doesntexist;
[][1];

should print:

PHP Notice:  Undefined variable: doesntexist in main.php on line 2
PHP Notice:  Undefined offset: 1 in main.php on line 3

I know the runner halts and captures when a warning or error is encountered but it doesn't appear to log notices. Is there a good reason not to print these notices on the runner?

I don't think so? I don't think there's anything specific to the runner.

No, it's not hidden intentionally and I don't know why it's not shown.

For PHP 7.4, the runner simply executes phpunit tests. phpunit.xml is

<phpunit printerClass="Codewars\PHPUnitCodewars\CodewarsResultPrinter">
</phpunit>

to use our custom reporter.

Maybe PHPUnit is capturing it and the custom reporter is missing something to output it.
