Description:
------------
The docs say
https://www.php.net/manual/en/function.pcntl-signal.php

> siginfo
> If operating systems supports siginfo_t structures, this will be an array of
> signal information dependent on the signal.

and in the changelog
> As of PHP 7.1.0 the handler callback is given a second argument containing the
> signinfo of the specific signal. This data is only supplied if the operating
> system has the signinfo_t structure. If the OS does not implement siginfo_t
> NULL is supplied.

(note: the page has a few "signinfo" typos)

but they don't give any more information than that.

Array keys according to PHP 7.4.0beta4:
https://github.com/php/php-src/blob/php-7.4.0beta4/ext/pcntl/pcntl.c#L1281
