Request: Send a blank email to internals+get-65577@lists.php.net to get a copy of this message 
Back in December I submitted a pull request to make FILTER_VALIDATE_INT
accept +0/-0. That request was merged into php-src:

https://github.com/php/php-src/pull/248

The other day I then stumbled upon a note on
http://www.php.net/manual/en/filter.filters.validate.php
saying "Numbers
+0 and -0 are not valid integers but validate as floats.", which makes
me wonder if the previous behavior (rejecting +0/-0) was on purpose
rather than by mistake?

Or should the documentation be adjusted to reflect the new behavior?
