301 PHP redirect not working

My goal: redirect www.innovationzen.com to innovationzen.com

I inserted the following code right at the top of the header.php
_______________________
<?php

if ($_SERVER['HTTP_HOST'] == "www.innovationzen.com") {
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://innovationzen.com".$_SERVER['REQUEST_URI']);
exit; }
?>
____________________________

However the redirect is not working, when i hit www.innovationzen.com I get the following:

"The document has moved here.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request."


Does anyone know what is wrong with the redirect?

thanks

 

Something like this ?

RewriteCond Host: www\.mysite\.com
RewriteRule (.*) http\://mysite.com$1 [I,R]

 

i need to do a php redirect becayse my host (yahoo) does not support .htaccess

I know it sucks but I am trying to set up the php before taking the more drastic action of changing host

 

Not tested.

Move exit; outside the if statement.

<?php if ($_SERVER['HTTP_HOST'] == "www.innovationzen.com") {
   header("HTTP/1.1 301 Moved Permanently");
   header("Location: http://innovationzen.com".$_SERVER['REQUEST_URI']);
}
exit;
?>

Code (markup):

Oh, and remove the empty line at the start. It matters in the header.
cheers,

gary
