One short question:
If I have a javascript script tag in a page that sets the src attribute
to a php script
Before I have the php script send the response via print or echo I
have to
call header('content-type: <?>');
so what would be the content type for javascript code?
text/javascript
or
application-x/javascript
or ?
Apologies if this is considered off topic
I have done this with css and used header('content-type text/css')
Also I figured out how to get a self processing page to send a
response to an ajax request sent to it by calling
header('content-type:text/plain')
for a plain text response.
Thank you for time and attention

That's actually quite a difficult question.
What you're basically asking is what is the mime-type of a javascript file.
The answer is that it is officially 'application/javascript'.
However, this has only recently been published as part of the standards.
Until just a few years ago, there was no agreed mime-type for javascript
files; this is why you'll see text/javascript, application/x-javascript,
etc. being used all over the place.
The HTML4, html5 and xhtml (1 and 1.1) speccs all expect a
text/javascript mimetype when using javascript.
In the end... it doesn't really matter that much. You could technically
send a mime-type of text/plain and it would still work just fine. This
is simply because most browsers don't trust the headers sent but tend to
take a peek into the first packets sent, and decide what it contains
based on that.
So... I'd personally use application/javascript since that's the
official mime-type. But it doesn't really matter that much which one you
use ;)
