php5 encoding problem turkish characters

Question

i have a php script which detects keyword density on given url.

my problem is, it doesn't detect turkish characters or deletes them..

i'm getting contents of url by file_get_contents method. this method works perfect and gets all content with turkish characters.

you can see my code on http://www.gazihanisildak.com/keyword/code.txt or try script on www.gazihanisildak.com/keyword

thanks..

You seem to be fetching and converting the file_get_contents data as UTF-8 (probably correctly), but your HTML page is not specifying an encoding for itself. So probably, any incoming form data is in iso-8859-1. Try specifying utf-8 as your page's encoding as well:

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