Edit report at https://bugs.php.net/bug.php?id=75733&edit=1 ID: 75733 Updated by: nikic@php.net Reported by: php-bug-reports at protonmail dot com Summary: count(null) and count(empty-string) raises a warning Status: Verified Type: Documentation Problem Package: Arrays related Operating System: Ubuntu, Windows PHP Version: 7.2.0 Block user comment: N Private report: N New Comment: It's a typo, s/not/now :) Previous Comments: ------------------------------------------------------------------------ [2017-12-26 10:09:12] requinix@php.net It is supposed to warn. https://wiki.php.net/rfc/counting_non_countables ------------------------------------------------------------------------ [2017-12-26 09:12:43] php-bug-reports at protonmail dot com Description: ------------ Since version of PHP 7.2.0 (stable) and 7.2.1 RC1 count() will raise a warning if argument is either null or empty string. It is hard to file this either as a bug, or documentation problem, because as stated in the manual (here: php.net/manual/en/function.count.php), examples are now obsolete / wrong. Additionally, in the same page in Changelog it is stated this, which adds even more to the confusion: Changelog Version Description 7.2.0 count() will not yield a warning on invalid countable types passed to the array_or_countable parameter. Test script: --------------- $s = ''; echo count($s); // returns 1 with a warning $n = null; echo count($n); // returns 0 with a warning $f = false; echo count($f); // returns 1 with a warning Expected result: ---------------- No warnings issued, or update documentation to include warnings issued. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75733&edit=1
