PHP插入条件

Question

I need to have some if conditions for some special characters. So what I basically want is to add some kind of 'if letter is oe make letter = "ø"' statement. How can I achieve this?

public function letter_get($letter)
    {
        $this->load->database();

        if($letter == '0-9')
        {
            $where = "formated_name LIKE '0%' OR formated_name LIKE '1%' OR formated_name LIKE '2%' 
            OR formated_name LIKE '3%' OR formated_name LIKE '4%' OR formated_name LIKE '5%' OR formated_name LIKE '6%' OR formated_name LIKE '7%' OR formated_name LIKE '8%' OR formated_name LIKE '9%' OR formated_name LIKE '#%'";
        }
        else  
        {
            $where = "formated_name LIKE '".$letter."%'";
        }

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

        if($data) {
            $this->response($data, 200); 
        } else {
            $this->response(array('error' => 'Couldn\'t find any artists with this letter!'), 404);
        }
    }

So can anyone help me out? That would be great! Thanks in advance...

You can replace the special characters with str_replace:

$letter = str_replace(array('oe', ... more inputs),
                      array('ø', ... more replacements),
                      $letter);
