Bug #75574 [Fbk]: putenv does not work properly if the parameter contains Chinese character

Edit report at https://bugs.php.net/bug.php?id=75574&edit=1 ID: 75574 Updated by: ab@php.net Reported by: ganlvtech at qq dot com Summary: putenv does not work properly if the parameter contains Chinese character Status: Feedback Type: Bug Package: Scripting Engine problem Operating System: Windows 10 (1709) zh-CN PHP Version: 7.1.12 Block user comment: N Private report: N New Comment: Ah, and the encoding of the file you've posted, too. Thanks. Previous Comments: ------------------------------------------------------------------------ [2017-11-26 21:04:14] ab@php.net Thanks for the report. Could you also tell whether your build is TS/NTS and what is your INI for default_charset and internal_encoding? Thanks. ------------------------------------------------------------------------ [2017-11-26 19:14:50] ganlvtech at qq dot com Description: ------------ If the value ends with odd numbers of Chinese characters, it returns false and getenv cannot get the environment variable just set. If the value ends with even numbers of Chinese characters, it works well and returns true. If the value ends with a ASCII character, although there are some Chinese characters in the string, it still works well. If the Chinese characters is split by ASCII character, only the number of the last part of Chinese characters affects the result. Japanese character also cause this problem. On ubuntu 16.04.3 with php 7.0.22 everything is OK. So the bug may be only for Windows. I have checked the php-src/ext/standard/basic_functions.c PHP_FUNCTION(putenv), but I'm sorry that I cannot find the solution. This problem might be similar to the fixed bug #50690(putenv() does not assign values to env. vars when the value is one character), but this one is for non-ASCII character. Thank you. Test script: --------------- <?php // Chinese character '啊' === urldecode('%E5%95%8A') var_dump(putenv('FOO=啊')); // false // var_dump(putenv('FOO=' . urldecode('%E5%95%8A'))); // false var_dump(putenv('FOO=啊啊')); // true // var_dump(putenv('FOO=' . urldecode('%E5%95%8A%E5%95%8A'))); // true var_dump(putenv('FOO=啊啊啊')); // false var_dump(putenv('FOO=啊啊啊啊')); // true // odd got false, even got true. var_dump(putenv('FOO=啊a')); // true var_dump(putenv('FOO=啊a啊')); // false var_dump(putenv('FOO=啊a啊a')); // true var_dump(putenv('FOO=啊a啊a啊')); // false var_dump(putenv('FOO=啊a啊啊')); // true var_dump(putenv('FOO=啊a啊啊啊')); // false var_dump(putenv('FOO=啊a啊啊啊啊')); // true // If the value ends with odd numbers of Chinese character, it returns false. ?> Expected result: ---------------- bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) bool(true) Actual result: -------------- bool(false) bool(true) bool(false) bool(true) bool(true) bool(false) bool(true) bool(false) bool(true) bool(false) bool(true) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75574&edit=1
