Bug #75574 [Csd]: putenv does not work properly if parameter contains non-ASCII unicode character

Edit report at https://bugs.php.net/bug.php?id=75574&edit=1 ID: 75574 User updated by: ganlvtech at qq dot com Reported by: ganlvtech at qq dot com Summary: putenv does not work properly if parameter contains non-ASCII unicode character Status: Closed Type: Bug Package: Scripting Engine problem Operating System: Windows 10 (1709) zh-CN PHP Version: 7.1.12 nts Win32 VC14 x64 Block user comment: N Private report: N New Comment: Using php.exe got expected result, but using php-cgi.exe putenv did not sets vars with Unicode. Test script: --------------- <?php var_dump(putenv('FOO=啊')); var_dump(echo %FOO%); // There will be a "\n" in the result. var_dump(getenv('FOO')); ?> Expected result: ---------------- bool(true) string(4) "啊 " string(3) "啊" Actual result: -------------- bool(true) string(3) "С " string(2) "С" The length of string is not equal to each other. putenv put vars using cp936 instead of Unicode. You can use another test script to view the difference. Test script: -------------- <?php var_dump(putenv('FOO=啊')); echo urlencode(echo %FOO%), PHP_EOL; echo urlencode(getenv('FOO')), PHP_EOL; ?> Expected result: ---------------- bool(true) %E5%95%8A%0A %E5%95%8A Actual result: -------------- bool(true) %B0%A1%0A %B0%A1 php snapshot: php-7.1-nts-windows-vc14-x64-r06202f0 Previous Comments: ------------------------------------------------------------------------ [2017-11-28 06:05:54] ganlvtech at qq dot com Tested the newest snapshot (7.1.13-dev nts). Using test script from php-src/ext/standard/tests/general_functions/putenv_bug75574_utf8.phpt Run 'php test.php', test passed. Run 'php -S 127.0.0.1:8000', and visit http://127.0.0.1/test.php, test passed. But when I run 'php-cgi -b 127.0.0.1:9000', and use nginx fastcgi_pass to php-cgi, putenv is OK, but getenv will return cp936 2-byte char instead of utf8 3-byte char. (In fact, I start php-cgi with 'RunHiddenConsole php-cgi -b 127.0.0.1:9000') I would test some more to find if there's some error in my setting. ------------------------------------------------------------------------ [2017-11-27 17:53:15] ab@php.net Automatic comment on behalf of ab Revision: http://git.php.net/?p=php-src.git;a=commit;h=2b7d283cc5589077d7ecc23cc9b2827759cab5c2 Log: Fixed bug #75574 putenv does not work properly if parameter contains non-ASCII unicode character ------------------------------------------------------------------------ [2017-11-27 10:18:06] ab@php.net Thanks for more info. Yeah, i guess the issue is that we the A versions of the API are used. Getting a VM with Chinese simplified to check more. Thanks. ------------------------------------------------------------------------ [2017-11-27 04:15:19] ganlvtech at qq dot com https://stackoverflow.com/questions/19008182/c11-and-win32-wchar-t if php uses SetEnvironmentVariableA now, it can convert UTF8 to UTF16 and use SetEnvironmentVariableW. I don't know if this is a solution of this problem. ------------------------------------------------------------------------ [2017-11-27 04:15:18] ganlvtech at qq dot com https://stackoverflow.com/questions/19008182/c11-and-win32-wchar-t if php uses SetEnvironmentVariableA now, it can convert UTF8 to UTF16 and use SetEnvironmentVariableW.
