Bug->Doc #77239 [Opn->Ver]: pathinfo strips umlauts only at the beginning

Edit report at https://bugs.php.net/bug.php?id=77239&edit=1 ID: 77239 Updated by: cmb@php.net Reported by: stephan dot eicher at check24 dot de Summary: pathinfo strips umlauts only at the beginning -Status: Open +Status: Verified -Type: Bug +Type: Documentation Problem Package: *Directory/Filesystem functions Operating System: Linux PHP Version: 7.1.24 Block user comment: N Private report: N New Comment: I assume that you get exactly the same output with basename(), for which the documentation already states: | If path contains characters which are invalid for the current | locale, the behavior of basename() is undefined. So, not a bug, but needs to be documented for pathinfo() as well. Previous Comments: ------------------------------------------------------------------------ [2019-02-05 13:53:07] alex dot a dot pott at gmail dot com This problem seems to be OS dependent. If I run the following script I get different results. Locally I'm running on MacOS Mojave use homebrew for PHP 7.2. Test script: --------------- <?php setlocale(LC_ALL, 'C'); var_dump(pathinfo('Ö Ü Å Ø äöüåøhello.txt')); Output using docker: --------------- docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp php:7.2-cli php test-locale-pathinfo.php array(4) { ["dirname"]=> string(1) "." ["basename"]=> string(29) " Ü Å Ø äöüåøhello.txt" ["extension"]=> string(3) "txt" ["filename"]=> string(25) " Ü Å Ø äöüåøhello" } Output locally: --------------- php test-locale-pathinfo.php array(4) { ["dirname"]=> string(1) "." ["basename"]=> string(31) "Ö Ü Å Ø äöüåøhello.txt" ["extension"]=> string(3) "txt" ["filename"]=> string(27) "Ö Ü Å Ø äöüåøhello" } ------------------------------------------------------------------------ [2018-12-04 19:32:07] stephan dot eicher at check24 dot de Description: ------------ Pathinfo will strip umlauts from the filename beginning if locale is not correct set. The strange thing is that it will not strip other umlauts for example if they are in the middle of the string. I would expect that it strips all umlauts or none but not that it will strip them from the beginning but not in the string. Test script: --------------- <?php setlocale(LC_ALL, 'C'); echo pathinfo('änderungs', PATHINFO_FILENAME) . PHP_EOL; echo pathinfo('bestandübertragung', PATHINFO_FILENAME) . PHP_EOL; Expected result: ---------------- änderungs bestandübertragung Actual result: -------------- nderungs bestandübertragung ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77239&edit=1
