PHP MySQL返回特殊字符

Question

How can I make this query also return special characters/danish letters (å, æ, ø)?

$sql = "SELECT artist_id, formated_name FROM artists WHERE formated_name LIKE '".$letter."%'";
$query = $this->db->query($sql);
$data = $query->result();

I read something about regex or str_replace ?

right now it returns %C3%A6 - when it comes to these letters...

thanks in advance...

Answer 1

%C3%A6 is percent encoded data .

You can decode it with urldecode .

It is an odd choice of format for data stored in a database, so you should probably look into fixing whatever adds the data to the database so that it stores the actual characters instead of the percent encoded versions of them.
