#41246 [Bgs]: Setting locales to german and applying utf8_encode to a float messes it up.

ID: 41246 User updated by: phil at goli dot at Reported By: phil at goli dot at Status: Bogus Bug Type: ICONV related Operating System: Linux Gentoo PHP Version: 5.2.1 New Comment: sorry for bothering but i'm quite sure there's something wrong. do you have locales installed on your machine? your code php -r 'setlocale(LC_ALL,"de_DE"); echo 10.01,"\n";' doesn't use utf8_encode which causes the problem together (and ONLY if locale de_DE is really installed on your system) with setlocale(LC_ALL,"de_DE"). so it doesn't prove that this is not a bug. please try these two lines: $loc_de = setlocale(LC_ALL,"de_DE"); echo 'Example only works if locale de_DE is installed! Current locale: "' . $loc_de . '". Output: ' . (utf8_encode(0.01) + 0.01) . "<br>"; Summary: a string that comes out of utf8_encode is not automatically type casted to float when adding another float to it (this would normally happen if you don't us utf8_encode). but this whole scenario is only the case if setlocale(LC_ALL,"de_DE") is used!

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php mike@honeybadger:~$ php -r 'echo 10.01,"\n";' 10.01 mike@honeybadger:~$ php -r 'setlocale(LC_ALL,"de_DE"); echo 10.01,"\n";' 10,01 ------------------------------------------------------------------------ [2007-05-01 00:00:37] phil at goli dot at Description: ------------ Applies to PHP versions 4.4.1, 4.4.4, 5.2.1, etc. 1. setlocales to german: setlocale(LC_ALL, 'de_DE@euro', 'de_DE', 'deu_deu'); 2. assign a float to a variable by defining a string: $myTest = '10.01'; 3. add a float to that string: $myTest = $myTest + 0.01; 4. convert that float to utf8: $myTest = utf8_encode($myTest); 5. add another float to that utf8 string: $myTest = $myTest + 0.01; 6. if the german locales are installed on the system then the output will be wrong. utf8_encode chops off the positions after decimal point. Reproduce code: --------------- $loc_de = setlocale(LC_ALL, 'de_DE@euro', 'de_DE', 'deu_deu'); echo '<html><body><form><textarea cols="40" rows="40">'; echo 'Preferred locale for german on this system is "' . $loc_de . '"' . "\n"; echo 'Example only works if locales for german are installed!' . "\n\n"; echo 'Normal:' . "\n"; $myTest = '10.01'; var_dump($myTest); $myTest = $myTest + 0.01; var_dump($myTest); // no utf8_encode $myTest = $myTest + 0.01; echo 'Result should be 10.03 and it is: '; var_dump($myTest); echo "\n\n" . 'With utf8_encode:' . "\n"; $myTest = '10.01'; var_dump($myTest); $myTest = $myTest + 0.01; var_dump($myTest); $myTest = utf8_encode($myTest); var_dump($myTest); $myTest = $myTest + 0.01; echo 'Result should be 10.03 BUT it is: '; var_dump($myTest); echo '</textarea></form></body></html>'; exit; Expected result: ---------------- Preferred locale for german on this system is "de_DE@euro" Example only works if locales for german are installed! Normal: string(5) "10.01" float(10,02) Result should be 10.03 and it is: float(10,03) With utf8_encode: string(5) "10.01" float(10,02) string(5) "10,02" Result should be 10.03 ... and it is: float(10,03) Actual result: -------------- Preferred locale for german on this system is "de_DE@euro" Example only works if locales for german are installed! Normal: string(5) "10.01" float(10,02) Result should be 10.03 and it is: float(10,03) With utf8_encode: string(5) "10.01" float(10,02) string(5) "10,02" Result should be 10.03 ... and it is: float(10,01) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41246&edit=1
