PHP：如何将html转换为unicode？

$url='%EA%B3%A0%EC%B9%B4%EC%A7%80%EB%85%B8';

echo '<a href="/'.$url.'">'.$url.'</a>';

And it shows the url is: mywebsite.com/고카지노 with anchor:

%EA%B3%A0%EC%B9%B4%EC%A7%80%EB%85%B8

Can you show me how to convert anchor to 고카지노? Thank you very much.

Use urldecode

$url = urldecode('%EA%B3%A0%EC%B9%B4%EC%A7%80%EB%85%B8');
echo "<a href='/$url'>$url</a>";

// Results in:
// <a href="/고카지노">고카지노</a>
