Question

I create a folder as follows.

function create(){
if ($this->input->post('name')){
    ...
            ...
    $folder = $this->input->post('name');
    $folder = strtolower($folder);
    $forbidden = array(" ", "å", "ø", "æ", "Å", "Ø", "Æ");
    $folder = str_replace($forbidden, "_", $folder);
    $folder = 'images/'.$folder;
    $this->_create_path($folder);
            ...

However it does not replace Norwegian character with _ (under bar)

For example, Åtest øre will create a folder called ã…test_ã¸re.

I have

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

in a header.

I am using PHP/codeigniter on XAMPP/Windows Vista.

How can I solve this problem?

Answer 1

Use this.

$string = $this->input->post('name');
$regexp = '/( |å|ø|æ|Å|Ø|Æ|Ã¥|ø|æ|Ã…|Ø|Æ)/iU';
$replace_char = '_';
