With php cURL get filename from file header
12,685
Solution 1
I know this question is kind of old, but I'd like to clarify CURLOPT_HEADERFUNCTION
a bit, I found the documentation on php.net to be confusing.
curl will send the header callback function one header at a time. The call back function must return the number of bytes read or else curl will fail (and the request will end)
curl_setopt($ch, CURLOPT_HEADERFUNCTION, "readHeader");
function readHeader($ch, $header)
{
// read headers
echo "Read header: ", $header;
return strlen($header);
}
Example output:
Read header: HTTP/1.1 200 OK
Read header: Server: nginx/0.8.32
Read header: Date: Wed, 31 Mar 2010 14:23:18 GMT
Read header: Content-Type: image/jpeg
Read header: Content-Length: 886308
Read header: Connection: close
Read header: Accept-Ranges: bytes
Read header:
Without the return from readHeader, curl will end after the first header is sent.
Solution 2
You need to assign a callback to read the headers.
curl_setopt($ch, CURLOPT_HEADERFUNCTION, readHeader);
function readHeader($ch, $header)
{
// read headers
}

I have this php cURL function:
function curl_login($url,$data,$proxy,$proxystatus){ $fp = fopen("cookietlt.txt", "w"); fclose($fp); $login = curl_init(); curl_setopt($login, CURLOPT_COOKIEJAR, "cookie.txt"); curl_setopt($login, CURLOPT_COOKIEFILE, "cookie.txt"); curl_setopt($login, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"); curl_setopt($login, CURLOPT_TIMEOUT, 40); curl_setopt($login, CURLOPT_RETURNTRANSFER, TRUE); if ($proxystatus == 'on') { curl_setopt($login, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($login, CURLOPT_HTTPPROXYTUNNEL, TRUE); curl_setopt($login, CURLOPT_PROXY, $proxy); } curl_setopt($login, CURLOPT_URL, $url); curl_setopt($login, CURLOPT_HEADER, TRUE); curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); curl_setopt($login, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($login, CURLOPT_POST, TRUE); curl_setopt($login, CURLOPT_POSTFIELDS, $data); ob_start(); // prevent any output return curl_exec ($login); // execute the curl command ob_end_clean(); // stop preventing output curl_close ($login); unset($login); } function curl_grab_page($site,$proxy,$proxystatus){ $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); if ($proxystatus == 'on') { curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE); curl_setopt($ch, CURLOPT_PROXY, $proxy); } curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt"); curl_setopt($ch, CURLOPT_URL, $site); ob_start(); // prevent any output return curl_exec ($ch); // execute the curl command ob_end_clean(); // stop preventing output curl_close ($ch); } curl_login('http://www.site.tdl/login.php','username=test&password=demo','','off'); curl_grab_page('http://www.site.tdl/1965.torrent','','off');
I need to get filename from file(http://www.site.tdl/1965.torrent) header into variable.
http://www.site.tdl/1965.torrent header:
Content-Disposition: attachment; filename="Linux.Mint.torrent" Content-Type: application/x-bittorrent Content-Length: 4525
So output will be Linux.Mint. How can I do that?
Thanks!
