PHP: Set UTF-8 Charset in HTTP Header
Question by Guest | 2015-07-03 at 22:00
Up to now, I have always specified the Charset (the character encoding) as meta tag within the head of my HTML page.
That is, for example
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
in HTML 4 or correspondingly the same in HTML 5:
<meta charset="UTF-8">
However, obviously, my server is nevertheless transmitting that my page is encoded in Latin 1 or ISO 8859-1. I do not know whether this can lead to problems in the browser, but I get the following error message when using an HTML Validator: The character encoding specified in the HTTP header (iso-8859-1) is different from the value in the element (utf-8).
Is there any possibility to modify the header with PHP so that the server is specifying UTF-8 as charset and content type correctly?

You can modify the header using the PHP function header(). In your case, that is the following line of code:
header('Content-Type: text/html; charset=utf-8');Important: You have to call this function before generating any output on your page. That means, before any echo and also before each character or space eventually written before your PHP code in your HTML page. Otherwise, the header would have already been sent and it would not be possible to change it anymore.
