PHP编码错误json_encode（）错误[关闭]

Question

I am running below code in PHP:

error_reporting(E_ERROR | E_PARSE);
header("Content-Type:application/json");
$version = GetFileVersion("../XXXXXXXXXX.exe");
$response = new \stdClass();
$response->version = $version;
$response = json_encode($response);
echo $response;
exit();

at URL: XXXXXXXXXXXXXXX

But I get:

{"version":"2\u00000\u00001\u00009\u0000.\u00007\u0000.\u00002\u00000"}

while I am expecting:

{ "version":"2019.7.20 }

What am I doing wrong?

GetFileVersion is defined here:

Answer 1

\uXXXX is the JSON Unicode escape notation.

if you are allowed to str_replace then use

echo str_replace('\\u00000', "", $response);

or use the JSON_UNESCAPED_UNICODE

json_encode($array, JSON_UNESCAPED_UNICODE)
