How to solve the php exec garbled problem?

php Fill in the pit exec or shell_exec cannot return Chinese garbled characters

Originally wanted to execute:

exec("python cmd.py",$str);
var_dump($str);

The cmd.py file output contains Chinese, and the result is displayed As shown in the picture below:

Many bloggers say that it can be solved by setting a predetermined encoding. For example, add the encoding before executing the command and then execute it:

$locale='en_US.UTF-8';
setlocale(LC_ALL,$locale);
putenv('LC_ALL='.$locale);
exec("python cmd.py",$str);
var_dump($str);

After trying it, I found that the problem still exists and it has no effect. . After a long search on Google, I finally found the solution, so I didn't dare to leave it alone, so I posted it to share. .

No nonsense, just go straight to it. . .

exec:
exec("python cmd.py",$str);
foreach($str as $res)
{
    $str = iconv("GBK", "UTF-8", $res);
}
echo $str;
shell_exec:
$res = shell_exec("python cmd.py");
echo iconv("GBK", "UTF-8", $res);

Both the exec and shell_exec returns above can display Chinese!
