PHP Function to Auto Generate Status Header
This is from the CodeIgnitor Common Functions Library. It is very useful:
// ------------------------------------------------------------------------
/**
* Set HTTP Status Header
*
* @access public
* @param int the status code
* @param string
* @return void
*/
if ( ! function_exists('set_status_header'))
{
function set_status_header($code = 200, $text = '')
{
$stati = array(
200 => 'OK',
201 => 'Created',
202 => 'Accepted',
203 => 'Non-Authoritative Information',
204 => 'No Content',
205 => 'Reset Content',
206 => 'Partial Content',
300 => 'Multiple Choices',
301 => 'Moved Permanently',

if ($code == '' OR ! is_numeric($code))

{

}
if ($text == '')
{
show_error('No status text available. Please check your status code number or supply your own message text.', 500);
}
$server_protocol = (isset($_SERVER['SERVER_PROTOCOL'])) ? $_SERVER['SERVER_PROTOCOL'] : FALSE;
