Hello,
I dont not know much of any php, i only know a few functions.
I have this script that i got a while ago:
PHP Code:
<?php
if(eregi(basename(__FILE__),$_SERVER['REQUEST_URI']))
die('You cannot access this file directly.');
function set_header()
{
$charset = "utf-8";
$mime = "text/html";
if(stristr($_SERVER["HTTP_ACCEPT"],"application/xhtml+xml")) {
if(preg_match("/application\/xhtml\+xml;q=0(\.[1-9]+)/i",
$_SERVER["HTTP_ACCEPT"], $matches)) {
$xhtml_q = $matches[1];
if(preg_match("/text\/html;q=0(\.[1-9]+)/i",
$_SERVER["HTTP_ACCEPT"], $matches)) {
$html_q = $matches[1];
if($xhtml_q >= $html_q) {
$mime = "application/xhtml+xml";
}
}
} else {
$mime = "application/xhtml+xml";
}
}
header("Content-Type: $mime;charset=$charset");
header("Vary: Accept");
if (stristr($_SERVER[HTTP_ACCEPT], "application/xhtml+xml"))
header("Content-Type: application/xhtml+xml; charset=utf-8");
else
header("Content-Type: text/html; charset=utf-8");
}
?>
And i just found this one posted somewhere in 2003:
PHP Code:
<?php
if ((isset($_SERVER["HTTP_ACCEPT"]) and
stristr($_SERVER["HTTP_ACCEPT"], "application/xhtml+xml")) or
stristr($_SERVER["HTTP_USER_AGENT"], "W3C_Validator") )
{
header("Content-type: application/xhtml+xml");
print("<?xml version=\"1.0\" encoding=\"utf-8\"?>\n");
}
else
{
header("Content-type: text/html; charset=utf-8");
}
?>
The first one is a bit more complex and longer and the 2nd is simple and shorter, but the results are about the same (except for the 2nd one it prints the xml line and tells the w3c validator what to see). What does the first one do because of all the lines that the 2nd one doesn't do?
BTW: the scripts add the application/xhtml+xml mime to supported browsers.
Thank You.
