How to get all server headers like Live http Headers does

dogfighter · November 27, 2009

Hey all, like many of you I use the Firefox addon "Live http Headers". I'm trying to write a tool that will basically do the same thing, but web-based... so the user would enter a URL and the tool would spit out the same output that Live http Headers would have shown if you were capturing them using it.

Problem is, sometimes the output from Live http Headers contains many requests of different types, for different things, on different servers. The PHP code I've been able to find in the manual pertaining to headers really only returns one (the last one).

What function should I be looking at if I want it to spit out ALL of the headers and requests, a-la the Firefox addon?

get_headers.

get_headers was the first thing I tried, but like I mentioned, it only returns one header in an array.

what do you mean, "only returns one header"?

get_headers was the first thing I tried, but like I mentioned, it only returns one header in an array.

It returns ALL the headers in one array, this should be very easy to parse and do much more than the 'live HTTP headers' addon. They use the same methods of retrieval, getting headers..

<?php
$url = 'http://www.example.com';

print_r(get_headers($url));

print_r(get_headers($url, 1));
?>

Expected result:

Array

    [0] => HTTP/1.1 200 OK
    [1] => Date: Sat, 29 May 2004 12:28:13 GMT
    [2] => Server: Apache/1.3.27 (Unix)  (Red-Hat/Linux)

Notice the blocks that are missing? Specifically the ones pertaining to the calls to various google services? I need everything, including those.

Then you will need to make requests to those sites just like your client (firefox) does.
