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: 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.

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.

I don't know if there is any settings wrong with my Windows (Chinese simplyfied version). It seems that the system only accept non-ASCII char in 2 bytes (in another word, system use GBK encoding). System accept & return the value in GBK encoding, but php pass & retrieve env var in UTF-8 encoding. I set an Environment variable in control panel, and retrieve the value in php by getenv. I got an GBK encoding byte string cannot read. Because php7 use UTF-8 as default ouput encoding. I tried echo iconv('GBK', 'UTF-8', getenv('FOO')); and got the expected value. I think this bug may be the limitation of Windows platform, and may not be fixed unless Windows change the its default encoding to Unicode. Thanks. Another test script: --------------- // Greek_alphabet 'α' === urldecode('%CE%B1') var_dump(putenv('FOO=α')); // true php.ini: --------------- ; PHP's default character set is set to UTF-8. ; http://php.net/default-charset default_charset = "UTF-8" ; PHP internal character encoding is set to empty. ; If empty, default_charset is used. ; http://php.net/internal-encoding ;internal_encoding = PHP Version: php-7.1.12-nts-Win32-VC14-x64 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
