How to select content type from HTTP Accept header in PHP

Question

I\'m trying to build a standard compliant website framework which serves XHTML 1.1 as application/xhtml+xml or HTML 4.01 as text/html depending on the browser support. Curre

Answer 1

Pear::HTTP 1.4.1 has a method string negotiateMimeType( array $supported, string $default)

 ',
    $http->negotiateMimeType( array('application/xhtml+xml', 'text/html'), 'application/xhtml+xml'),
    "\n";
}

prints

text/*;q=0.3, text/html;q=0.7, text/html;level=1, text/html;level=2;q=0.4, /;q=0.5 -> application/xhtml+xml
text/*;q=0.3, text/html;q=0.8, application/xhtml+xml;q=0.7, */*;q=0.2 -> text/html
text/*;q=0.3, text/html;q=0.7, */*;q=0.8 -> application/xhtml+xml
text/*, application/xhtml+xml -> application/xhtml+xml
text/html, application/xhtml+xml -> text/html

edit: this might not be so good after all...
My firefox sends Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8
text/html and application/xhtml+xml have q=1.0 but PEAR::HTTP (afaik) doesn't let you chose which one you prefer, it returns text/html no matter what you pass as $supported. This may or may not be sufficient for you. see my other answer(s).
