Edit report at https://bugs.php.net/bug.php?id=73655&edit=1 ID: 73655 Comment by: me at kelunik dot com Reported by: sjon at hortensius dot net Summary: Spoofchecker::isSuspicious broken Status: Open Type: Bug Package: I18N and L10N related PHP Version: 7.1.0 Block user comment: N Private report: N New Comment: Works for me with ICU 55, so it seems to be an ICU problem. $ php -v PHP 7.1.0 (cli) (built: Dec 5 2016 17:15:16) ( NTS DEBUG ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.1.0-dev, Copyright (c) 1998-2016 Zend Technologies $ cat bug73655.php <?php $checker = new Spoofchecker(); var_dump($checker->isSuspicious('google.com')); var_dump($checker->isSuspicious('Рaypal.com')); $ php bug73655.php bool(false) bool(true) $ apt-show-versions libicu-dev libicu-dev:amd64/xenial 55.1-7 uptodate libicu-dev:i386 not installed Previous Comments: ------------------------------------------------------------------------ [2016-12-05 16:22:21] sjon at hortensius dot net I have confirmed php-7.1.0 compiled with ICU 55 works fine. Compiled with ICU 57 also works. Can anyone confirm if this is a bug with ICU itself; or with PHP's usage of ICU? This is still a problem as distros such as ArchLinux will soon release with ICU-58 and experience this issue ------------------------------------------------------------------------ [2016-12-05 15:51:11] sjon at hortensius dot net This might also be related to the recently released ICU-58 (http://site.icu-project.org/download/58) with which 7.1 was compiled. I'm sure distros will compile with the same ICU but this might be the reason I didn't find a suspicious commit in php-src itself ------------------------------------------------------------------------ [2016-12-05 15:31:08] sjon at hortensius dot net Description: ------------ It seems Spoofchecker::isSuspicious is broken; testing an example from the manual all PHP versions work fine; except 7.1.0. This seems related to an update which was done to the localization which was not present in any of the RCs (insert rant about RCs being real RCs here) Test script: --------------- See https://3v4l.org/5HWQT, script was copied from http://php.net/manual/en/spoofchecker.issuspicious.php <?php $checker = new Spoofchecker(); var_dump($checker->isSuspicious('google.com')); var_dump($checker->isSuspicious('Рaypal.com')); Expected result: ---------------- bool(false) bool(true) Actual result: -------------- bool(false) bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73655&edit=1
