PHP：获取编码的html实体

Question

I'm trying to get the html entities of a UTF-8 string,
Example: example.com/search?q=مرحبا

<?php
    echo htmlentities($_GET['q']);
?>

I got:

مرحبا0مرحبا

It's UTF-8 text not html entities, what I need is:

مرحبا

I have tried urldecode and htmlentities functions!

Add this code to the start of your file:

header('Content-Type: text/html; charset=utf-8');

The browser needs to know it is UTF-8. This tag also can go in the head section for formality.

<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
