I`m building some portable application.
And I need to know the value of FD_SETSIZE to prevent socket_select from 'crashing'

simply (?) defining FD_SETSIZE would be greate

In my opinion, it would be better to fix the crashing
socket_select(). So please specify the details of the crash. Is it
the same behavior as reported in bug #72030?

No, IIRC (and it was 9 years ago) it was just a nice error complaining about passing in fds higher than 1024/FD_SETSIZE. I'm somewhat certain it didn't actually crash, but just returned an error.

Then I assume it was the message reported in bug #69637. I'd still
prefer to fix that issue, but making available the value of
FD_SETSIZE to userland might be desirable anyway, so I've
submitted a respective PR.

This feature request has been implemented. FD_SETSIZE will be
available as PHP_FD_SETSIZE as of PHP 7.1.0.
