Hello Keith!

This was very interesting reading and I have given this a serious thought and I will now do the same on my site. I only wonder if there are any specific reason to explode the HTTP_ACCEPT string and the check for values with in_array istead of using strpos? My HTTP_ACCEPT looks like this: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,[wrapped -- ed]
text/plain;q=0.8,video/x-mng,image/png,image/jpeg,image/gif;q=0.2,/;q=0.1
and as you se there is semi colons as well so exploding this and picking the first four would give me:
[0] => text/xml
[1] => application/xml
[2] => application/xhtml+xml
[3] => text/html;q=0.9
Imagine if it the UA had switched place on text/html and application/xhtml+xml then the first four would yield:
[0] => text/xml
[1] => application/xml
[2] => text/html
[3] => application/xhtml+xml;q=0.9
Wouldn´t in_array fail to find the application/xhtml+xml here? It would of course fall back on the bullet proof text/html but I would only like to get your heads up on this issue, if it´s now is an issue ;-)
As I asked earlier: If there is any good reason to explode it and do the search in the array, please let me know because I think it´s a brilliant solution.
By the way. I just finished reading some WDs from the W3Cs site and they have a really good document if you haven´t read it yet give it (http://www.w3.org/TR/i18n-html-tech-lang/) a glance.

Cheers

Andrin, that's a good point. I was aware of the issue but chose to ignore it because I don't believe it will come up often in practice (since if anything, text/html will be the content-type listed with reduced quality, not application/xhtml+xml), and because I default to text/html anyway which will work fine as a fallback.

The main reason I did it the way I did was just personal preference. I may choose to improve the parser to take care of the issue you highlighted.

By the way, that i18n document from the W3C you linked to I already linked to on the post I referenced from this post. Thanks though.

You can pass "auto" as the encoding to mb_convert_encoding(), which means you didn't have to use the UTF-8 detector.

I think I remember trying that and it not doing what I wanted. Thanks for the note though. If I ever need to do something like this again I'll make sure to try it.
