使用file_get_contents时忽略Content-Length标头

Question

I need to get the contents of a page, which always sends a Content-Length: 0 header, however the page is never empty.

The file_get_contents(url) just returns an empty string.

The whole header returned by the page is:

HTTP/1.1 200 OK
X-Powered-By: PHP/5.3.10
Expires: Mon, 26 Jul 1997 05:00:00 GMT
Last-Modified: Sat, 18 Feb 2012 18:14:59 GMT
Cache-Control: no-store, no-cache, must-revalidate
Cache-Control: post-check=0, pre-check=0
Pragma: no-cache
Content-Type: text/html; charset=UTF-8
Content-Length: 0
Date: Sat, 18 Feb 2012 18:14:59 GMT
Server: lighttpd

Would it be possible to use file_get_contents and ignore the header or do I need to use curl?

Edit

get_headers(url) output (using print_r ):

Array
(
    [0] => HTTP/1.0 200 OK
    [1] => X-Powered-By: PHP/5.3.10
    [2] => Content-type: text/html
    [3] => Content-Length: 0
    [4] => Connection: close
    [5] => Date: Sat, 18 Feb 2012 22:39:52 GMT
    [6] => Server: lighttpd
)

Answer 1

As noted by Optimist the problem had nothing to do with the headers, but rather that I didn't send any User-Agent header to the server.

file_get_contents worked perfectly after sending User-Agent headers, even though the server always returns Content-Length: 0 .

Weird.

Answer 2

I believe, that none of HTTP-level functions can not read such an answer. Because it is incorrect HTTP answer, it says "my body is empty, dont read it"

You definitely need your own function based on fread, which will phisically read the socket. Something like this:

$aURL    = parse_url($sURL);

if ($iHandle = fsockopen($aURL["host"], 80, $iError, $sError))
{
    $sQuery = substr($sURL, strpos($sURL, $aURL["host"]) + strlen($aURL["host"]));

    $sOut   = "GET " . (($sQuery != "") ? $sQuery : "/") . " HTTP/1.1\r\n";
    $sOut  .= "Host: " . $aURL["host"] . "\r\n";
    $sOut  .= "Connection: Close\r\n\r\n";

    fputs($iHandle, $sOut);

    while (!feof($iHandle))
    {
        $sResult .= fread($iHandle, 1024);
    }
}

Then just cut the headers.
