I tried using header function but that didn't help me!
You need to do three things:
- Make sure you're receiving the data as UTF-8 data. For MySQL, query
SET NAMES 'utf8'
before selecting records. - Make sure you're using UTF-8 compatible functions when dealing with UTF-8 strings.
- Make sure you're setting the output encoding as UTF-8. For HTML, this can be done by setting the
Content-type
HTTP header to (e.g.)text/html; charset=utf-8
.
Of course, replace "UTF-8" with whatever encoding you want which supports the characters you need. There's no need to change the database tables (except for possible performance gains). You may need to change HTML templates, etc. if you decide on UTF-16 or something else which isn't (mostly) ASCII-compatible.
You need to declare the used character encoding in the HTTP response. You can use the header
function:
header('Content-Type: text/html;charset=utf-8');
With this the output is declared to be HTML with the character encoding UTF-8. Note that you can’t use header
when you’ve already sent data to the client without buffering it. So either use the output control to buffer the output so that you can modify the header although there already was some output or use header
before any output.
Maybe I'm a little too late but this worked for me:
echo utf8_encode('سلام');
