getheaders & curl returning different OK response codes

[Anjanesh]

I'm not sure if this is a google storage issue.

I have a php snippet that does this :

<?php

$img = "http://commondatastorage.googleapis.com/bucket/path/to/object.jpg";

$headers = get_headers($img);

print_r($headers);

?>

php getheaders.php 

Array

(

    [0] => HTTP/1.0 200 OK

    [1] => Server: HTTP Upload Server Built on Mar 6 2013 16:24:27 (1362615867)

    [2] => Date: Wed, 13 Mar 2013 10:46:01 GMT

    [10] => Content-Language: en

    [11] => x-goog-hash: md5=lA5eWMUzyacVgTK6vQvkOw==

    [12] => Accept-Ranges: bytes

    [13] => Content-Length: 24977

    [14] => Vary: Origin

)

But on using curl :

curl --head http://commondatastorage.googleapis.com/bucket/path/to/object.jpg

HTTP/1.1 200 OK

How is that getheaders() returned "HTTP/1.0 200 OK" while curl returned "HTTP/1.1 200 OK" ? Im on Ubuntu 12.10.

Hello Anjanesh,

The HTTP version in use in this case is based on the HTTP version sent by the client.  The fact that the PHP code resulted in an HTTP/1.0 response merely indicates that PHP made an HTTP 1.0 request, wherease curl made an HTTP 1.1 request. 

In this particular case, though, it looks like you want to be making a HEAD request, so you'll want to use the php function http_head, rather than the get_headers function you're currently using. I hope this helps.
