I met with a PHP messy characters issue. Although it maybe a simple or basic question, it hasn't been solved until now after hours googling. I run the following simple snippet to access an unreachable IP, and echo $errstr.

<?php
header("Content-type: text/html; charset=utf-8");
$socket = fsockopen("10.180.100.100", "23", $errno, $errstr, 3);// IP which can't access
echo $errstr."<br/>";
echo mb_detect_encoding($errstr)."<br/>";

When I run it from PHP CLI, the result is what I expect.

When I access it from my Apache server, I get messy characters.

I have set header("Content-type: text/html; charset=utf-8"), and set page encoding as UTF-8. Neither is helpful.

Any ideas why?

Messy :) Thats UTF-8 characters most likely – RiggsFolly Aug 25 '20 at 14:11
Make sure that the `encoding_test.php` code file is also UTF-8 encoded and you will see UnMessy text – RiggsFolly Aug 25 '20 at 14:15
And in Apache start the page with ` ` – RiggsFolly Aug 25 '20 at 14:18
I don't get the same thing, of course I don't have whatever generates that debug table. – AbraCadaver Aug 25 '20 at 14:19
@RiggsFolly The file is encoded as UTF-8. I use vscode and can see it clearly. I have added the code you provided, but not helpful. – Does Aug 25 '20 at 14:47
Read the rest of the DUP then, somewhere in there is somethng that will help – RiggsFolly Aug 25 '20 at 14:49
@AbraCadaver So it maybe an enviroment issue. But I still don't know how to resolve. – Does Aug 25 '20 at 14:50
@RiggsFolly Thank you. I will read it immediately. – Does Aug 25 '20 at 14:52
