Force encoding in utf-8 for a php page

Question

I have a VPS (Debian, Apache, MySQL, PHP)

I want to force the encoding in UTF-8. I have put this line :

header('Content-type: application/json; charset: UTF-8');

But the charset is still ISO8859

I also edited the php.ini : /etc/php5/apache2/php.ini

mbstring.language=UTF-8
mbstring.internal_encoding= UTF-8
mbstring.http_input=UTF-8
mbstring.http_output=UTF-8
mbstring.detect_order= auto

and the apache conf :

nano /etc/apache2/conf.d/charset
AddDefaultCharset UTF-8

An iOS application is calling my php page. And I give it a JSON output. But it receives ISO charset...

When you say "the charset is still ISO8859", what do you mean? Where do you see that value? — Mark Reed

I look the page information (right button in Firefox) the encoding is ISO. I have a json output. — geekInside

Your response header is incorrect:

header('Content-type: application/json; charset: UTF-8');

It should be:

header('Content-type: application/json; charset=UTF-8');

Notice the = in place of :

Did you take a look at the utf8-encode function: http://php.net/manual/en/function.utf8-encode.php ?

You may be echoing non-properly encoded text to the client. Apache does not do this for you.

Did you check if you have any warning message that could help in the error console?

Oh. Figured it. Your header is wrong, you should have Content-type: application/json; charset=UTF-8 instead of Content-type: application/json; charset: UTF-8.

In .htaccess file you can put:

php_value default_charset UTF-8
