PHP get_headers() reports different headers than CURL

Question

How is it possible that get_headers() could possibly return a different result than getting them by CURL? Here is my code:

header(\"Content-type         


        

Answer 1

Add a different User-Agent header before get_headers:

stream_context_set_default(
    array(
        'http' => array(
            'method' => 'HEAD',
            'header' => "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.79 Safari/537.1\r\n"
        )
    )
);

And, might as well specify HEAD since you only want headers. With this change you get the right headers.

    [3] => Content-Type: text/html;charset=UTF-8
    [4] => Cache-Control: max-age=76
    [5] => Date: Fri, 31 Aug 2012 07:53:24 GMT
    [6] => Connection: close
)
