PHP Headers and Popular Mime Types

By  on  

Like my Create a Basic Web Service Using PHP, MySQL, XML, and JSON illustrates, even though a file's extension ends in PHP, you can still tell the browser that you're outputting a different content type. Here are a few of the more popular content types used on the internet.

Atom

header('Content-Type: application/atom+xml');

CSS

header('Content-Type: text/css');

Javascript

header('Content-Type: text/javascript');

JPEG Image

header('Content-Type: image/jpeg');

JSON

header('Content-Type: application/json');

PDF

header('Content-Type: application/pdf');

RSS

header('Content-Type: application/rss+xml; charset=ISO-8859-1');

Text (Plain)

header('Content-Type: text/plain');

XML

header('Content-Type: text/xml');

Just because a file ends in .PHP doesn't mean it responds with XHTML -- respond however you'd like!

    Create Namespaced Classes with MooTools

    MooTools has always gotten a bit of grief for not inherently using and standardizing namespaced-based JavaScript classes like the Dojo Toolkit does.  Many developers create their classes as globals which is generally frowned up.  I mostly disagree with that stance, but each to their own.  In any event...

    7 Essential JavaScript Functions

    I remember the early days of JavaScript where you needed a simple function for just about everything because the browser vendors implemented features differently, and not just edge features, basic features, like addEventListener and attachEvent.  Times have changed but there are still a few functions each developer should...

  1. Great list of mime types.
    Perhaps I’d just be careful about the charset at the RSS example. People could add it blindly and suddenly accented characters would stop working if the rest of the site is using other encodings, like utf-8.

  2. Interesting list. Nothing new, but still nice. BTW Javascript and XML should be application, text is obsolete.

  3. @Matěj Grabovský: Interesting. Can you share your resource for knowing that?

  4. @David Walsh: Well, especially Wikipedia, RFCs (concretely RFC3023) and this thing.

  5. Thank you for sharing Matěj!

  6. You’re welcome, sir!

  7. BTW, It is common to prefix experimental mime types with ‘x-‘ (e.g. application/x-json)

  8. Very usefull stuff, I suggest you ad this one too (exe, zip, rar…)

    header("Content-Type: application/force-download");
    

    BTW, 7 comments, since may 7th… and it’s 7 a.m. here in Morocco

  9. Thanks a lot for this information.

  10. Content-Type or Content-type ?

  11. Have been using just the java, css and htmls. Will do with the rest later.
    Thanks for the list David.
    Pleasure reading.
    ;)

  12. Perfect list! Just what I was looking for. Thanks, Mr. Walsh :-)

    $i = $r->new_child(“item”);
    $i->new_child(“title”, $head);
    $i->new_child(“link”, $link);
    $i->new_child(“description”, $comment);

    $out = domxml_dumpmem($doc);
    $file = $arch . “.xml”;
    $f = fopen($file, ‘w’);
    fputs($f, $out);
    fclose($f);

    echo $out;

  14. Really nice, that’s exactly what I was looking for!
    Thanks a lot David, for another great tutorial.
