How to set HTTP header to UTF-8 using PHP which is valid in W3C validator

Question

I have several PHP pages echoing out various things into HTML pages with the following code    lt meta http-equiv  Content-type  content  text html  charset utf-8    gt    However  when I validate using the W3C validator it comes up with      The character encoding specified in the HTTP header  iso-8859-1  is different from the value in the  element  utf-8     I am quite new to PHP  and I was wondering if I could and should change the header for the PHP files to match the HTML files

This is a problem with your web server sending out an HTTP header that does not match the one you define. For instructions on how to make the server send the correct headers, see this page.

Otherwise, you can also use PHP to modify the headers, but this has to be done before outputting any text using this code:

header('Content-Type: text/html; charset=utf-8');

More information on how to send out headers using PHP can be found in the documentation for the header function.

First make sure the PHP files themselves are UTF-8 encoded   The meta tag is ignored by some browser  If you only use ASCII-characters  it doesn t matter anyway   http   en wikipedia org wiki List of HTTP header fields  header  Content-Type  text html  charset utf-8

Use header to modify the HTTP header   header  Content-Type  text html  charset utf-8      Note to call this function before any output has been sent to the client  Otherwise the header has been sent too and you obviously can   t change it any more  You can check that with headers sent  See the manual page of header for more information
