I know what the [`error_reporting` values mean](https://www.php.net/manual/en/function.error-reporting.php#refsect1-function.error-reporting-examples). I know `-1` means "show all" and `0` means "show none".

But nowhere is specified what is the value set by default, when nothing is specified by the user.

Trying `phpinfo()` I see

```
...
Configuration File (php.ini) Path => /usr/local/etc/php
Loaded Configuration File => (none)
...

```

So, given there's no `php.ini` loaded, **what is the default value/behaviour of `error_reporting`?**
