Edit report at https://bugs.php.net/bug.php?id=67745&edit=1 ID: 67745 Updated by: tyrael@php.net Reported by: pascal dot chevrel at free dot fr Summary: regression in RC2: failing test with Atoum, not failing with php 5.4 and 5.5 -Status: Verified +Status: Not a bug Type: Bug Package: *General Issues Operating System: Linux PHP Version: 5.6.0RC2 Assigned To: tyrael Block user comment: N Private report: N New Comment: the result of the sort is different, because mb_strlen returns a different value on 5.6, because the default mb_internal_encoding was changed in 5.6 from ISO-8859-1 to UTF-8: http://3v4l.org/rZNL4 this change is described in our UPGRADING guide and should be explained in the php.net upgrading docs also: http://git.php.net/?p=php-src.git;a=blob;f=UPGRADING;h=7a174c47c2a034ac3718cf364cde66569d72b0d7;hb=refs/heads/PHP-5.6#l80 if you want to make sure that your code/test produces the same result on both 5.6 and older versions (or anywhere where the internal encoding is set to a non-default value), consider explicitly passing the second optional $encoding argument to mb_strlen() Previous Comments: ------------------------------------------------------------------------ [2014-08-02 11:05:43] tyrael@php.net yeah, I've seen it, and it depends on atoum, and it makes the work for us easier if we don't have to get ourself familiar with each and every php project to be able to find out what exactly causes the problem, I've went ahead and created a simple reproduce script based on your repo: <?php $sentence = 'Le système le style du couteau du suisse'; $words = explode(' ', $sentence); $words = array_filter($words); // filter out extra spaces $words = array_unique($words); // remove duplicate words // sort words from longest to shortest usort( $words, function ($a, $b) { return mb_strlen($b) - mb_strlen($a); } ); var_dump($words); ------------------------------------------------------------------------ [2014-08-02 10:18:39] pascal dot chevrel at free dot fr There is a testcase in a github repo referenced in this bug. ------------------------------------------------------------------------ [2014-08-02 10:16:08] tyrael@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2014-08-02 09:29:46] pascal dot chevrel at free dot fr Description: ------------ I have a test failing with PHP 5.6RC2, I don't know if it is a bug in Atoum or if it exposes a regression in the upcoming PHP 5.6 release. I put a repo online with a reduced test case exposing the bug: https://github.com/pascalchevrel/atoumbug_php5.6 I also filed a bug on Atoum: https://github.com/atoum/atoum/issues/346 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67745&edit=1
