Edit report at https://bugs.php.net/bug.php?id=77278&edit=1 ID: 77278 Comment by: spam2 at rhsoft dot net Reported by: spam2 at rhsoft dot net Summary: floatval(strval(value)) truncates if locale's decimal_point isn't a period Status: Verified Type: Bug Package: Scripting Engine problem PHP Version: Irrelevant Block user comment: N Private report: N New Comment: ok, you can partially repdoduce that behavior echo (string)4/3, "\n"; setlocale(LC_ALL, 'en_US.UTF-8'); echo (string)4/3, "\n"; setlocale(LC_ALL, 'de_DE.UTF-8'); echo (string)4/3, "\n"; ------------------------------- BUT YOU CANN NOT GET THE CURRECT LOCALE WITH PHP echo (string)4/3, "\n"; setlocale(LC_ALL, 'en_US.UTF-8'); echo setlocale(LC_ALL, NULL), "\n"; echo (string)4/3, "\n"; setlocale(LC_ALL, 'de_DE.UTF-8'); echo setlocale(LC_ALL, NULL), "\n"; echo (string)4/3, "\n"; [harry@srv-rhsoft:/downloads]$ php test.php 1.3333333333333 de_DE.UTF-8 1,3333333333333 de_DE.UTF-8 1,3333333333333 ------------------------------- why don't that shit mention 'en_US.UTF-8' which i would have liked to put at the libtidy bugreport instead wasting all my time with assumptions? there is anyways no sibgle pojnt of have TYPECASTS behave different - that's what format functions are! Previous Comments: ------------------------------------------------------------------------ [2018-12-10 21:45:13] spam2 at rhsoft dot net nonsense! show me the PHP code where type casts after setlocale() change tehir meaning! you can't even distinct what happens by use setlocale('whatever', NULL) before and after the tidy call because i get always get de_DE.UTF-8 as result ------------------------------------------------------------------------ [2018-12-10 21:41:36] requinix@php.net You can't blame PHP for Tidy's problem. If they change locale (already a dangerous operation since it's not thread-safe) and then don't revert it to the previous setting when they're done, that's their fault. ------------------------------------------------------------------------ [2018-12-10 21:33:13] spam2 at rhsoft dot net working as intended? a random linked library calls locale and the whole behavior of internal php typecast changes for every follow-up code in a PHP application is intended? really? ------------------------------------------------------------------------ [2018-12-10 21:29:50] nikic@php.net I think we should get rid of the locale-dependent float to string cast in PHP 8, but for now this is working as "intended". We should definitely *not* make string to float cast locale-sensitive as well, that would only make a bad situation worse. ------------------------------------------------------------------------ [2018-12-10 19:37:59] requinix@php.net var_dump(setlocale(LC_NUMERIC, "de_DE", "German_Germany")); var_dump(1 / 2); float 0,5 var_dump(strval(1 / 2)); // string "0,5" var_dump(floatval(strval(1 / 2))); // float 0 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
