Answer 1

Client may accept a list of mime-types in the response. In the other hand the order of the response is very important for client side. PHP Pear HTTP2 is the best to deal with language, charset, and mimetypes.

$http = new HTTP2();
$supportedTypes = array(
    'text/html',
    'application/json'
);

$type = $http->negotiateMimeType($supportedTypes, false);
if ($type === false) {
    header('HTTP/1.1 406 Not Acceptable');
    echo "You don't want any of the content types I have to offer\n";
} else {
    echo 'I\'d give you data of type: ' . $type . "\n";
}
