laravel-php putenv function Chinese cannot use the problem

If you know laravel can look at the above piece, if you do not know, go straight to the dividing line below;

Any of the Env items here take mail_driver as an example
Change to "my" with the ENV function can get to the value of normal;
Instead of "I" with the ENV function can not be obtained normally;

MAIL_DRIVER=我var_dump(env(MAIL_DRIVER''));  // NULLMAIL_DRIVER=我的var_dump(env(MAIL_DRIVER''));  // 我的

Some other Chinese such as "good" will also appear this situation;
Have to say, laravel and profound; study the ENV function source code;
The last problem to locate is;
-------------------------------------------------understand and don't understand the split line of the Laravel frame------------------------------------------------

putenv("PROJECT_NAME=我的");phpinfo();

Environment in phpinfo can be searched for project_name

putenv("PROJECT_NAME=我");phpinfo();

Environment in phpinfo can not be searched project_name

Ask the parents, why is this? How to set the Chinese value without obstacles?

I also tried it and found that as long as the call in the CGI environment putenv('PROJECT_NAME=掉') (four bytes, the Japanese kana is the same) will fail false to return, and in the CLI environment is not a problem:

I also feel quite fascinated, Google a bit also can not find similar situation, expect others to have a good answer.

But since the main use is Laravel, and not particularly rigidly putenv , just want to get .env the value of the words, you can use a few tips:

Add this function to your own project helpers.php (or to any other place where you put a custom help function):

if (! function_exists (' menv ')) {/** * Gets the value of a environment variable by getenv () or $_env. * * @param string $key * @param mixed $default * @return Mixed * * function menv ($key, $default = n ull) {if (function_exists (' putenv ') && function_exists (' getenv ')) {//try to read by getenv            () $value = getenv ($key);            if ($value = = = False) {return value ($default); }} else {//try to read from $_env or $_server if (Isset ($_env[$key])) {$va            Lue = $_env[$key];            } elseif (Isset ($_server[$key])) {$value = $_server[$key];            } else {return value ($default); }} switch (Strtolower ($value)) {case ' true ': Case ' (true) ': Return TR            Ue            Case ' false ': Case ' (false) ': return false; Case' Empty ': Case ' (empty) ': return ';        Case ' null ': Case ' (null) ': return;            } if (strlen ($value) > 1 && str::startswith ($value, ' "') && str::endswith ($value, '" ')) {        Return substr ($value, 1,-1);    } return $value; }}

Customize a new function to get the environment variable, and config/ replace all of the directories env menv (I tried $_ENV , $_SERVER the write will not be affected)

can refer to here, originally I for some users can not use the processing is just putenv
