#25246 [Bgs]: broken locale support for decimal_point

ID: 25246 User updated by: david at boe dot es Reported By: david at boe dot es Status: Bogus Bug Type: Scripting Engine problem Operating System: linux PHP Version: 4.3.2 New Comment: Hi! I'm sorry about the bogus status of my recent submission, but i think that you are not carefully considering this problem. The problem was not considered a bug sometime ago, but that doesn't mean it isn't. I've read severak times the reasons you mention, and i think the solution is not correct. The reason given a year ago was: You should not use ',' to represent floats ALWAYS use '.' regardless of locale. This is not a genuine reason, just because, databases returns their values in locale format (1,5 instead of 1.5). There is not a workaround solution for applications manipulating those values (maybe an oci8 function returning floats always with "."). Please, consider this problem as a real one, because, it will make us stick with older versions of php that respect the locale output returned from Oracle. Thanks for any help. Yours, David.

This breaks backward compatibility, at least with PHP 4.2.3 This is BAD as long as we use na Oracle database with NLS_LANG=Spanish_Spain.WE8ISO8859P1 , needed to output regional chars like ñ and áéíóú. This means that all operations with numerical values returned by a database query (decimal part separated by ',') are broken now. In my linux: [root@farm2 root]# export LANG=es_ES [root@farm2 root]# locale -k decimal_point decimal_point="," The script: <?php setlocale(LC_ALL, 'es_ES'); $locale_info = localeconv(); echo "decimal_point: {$locale_info["decimal_point"]}\n"; $value1="1.5"; $value2="1,5"; $res1=$value1*1; $res2=$value2*1; echo "Res 1 : $res1 \n"; echo "Res 2 : $res2 \n"; ?> outputs: decimal_point: . Res 1 : 1,5 Res 2 : 1 Reproduce code: --------------- In my linux: [root@farm2 root]# export LANG=es_ES [root@farm2 root]# locale -k decimal_point decimal_point="," The script: <?php setlocale(LC_ALL, 'es_ES'); $locale_info = localeconv(); echo "decimal_point: {$locale_info["decimal_point"]}\n"; $value1="1.5"; $value2="1,5"; $res1=$value1*1; $res2=$value2*1; echo "Res 1 : $res1 \n"; echo "Res 2 : $res2 \n"; ?> outputs: decimal_point: .
