Return only parsed data from fsockopen connection

[epetoke]

Hi all,

I am using fsockopen to post a string to an external web site via the get method using the following code:

$fp = fsockopen("www.website.com", 80, $errno, $errstr, 30); 

fputs($fp, "GET /friend.php?id=0123456&af=60067 HTTP/1.0\r\n"); 
fputs($fp, "Host: www.website.com\r\n"); 
fputs($fp, "Connection: Close\r\n\r\n"); 

while (!feof($fp)) { 
$data .= fgets($fp, 1024); 
} 

echo "$data";

That works just fine in terms of opening a connection and returning the data but the problem it returns a whole load of data i don't need:

HTTP/1.1 200 OK Connection: close Date: Mon, 27 Feb 2006 18:27:24 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET Content-Length: 23 Content-Type: text/html Expires: Mon, 27 Feb 2006 01:47:23 GMT Set-Cookie: ASPSESSIONIDQADRBTBS=GIEGHLFBKKKFOHIBCEBBJOGC; path=/ Cache-control: private Confirmed - 2385056

The only bit i'm interested in is the bit right at the bottom that says 'Confirmed - 2385056'

If the full url was pasted into the browser the parsed page will only display 'Confirmed - 2385056'

Is there a way I can add something to my code to make fsockopen only return the parsed part of the page and forget all the other header info?

Thanks in advance

Couldn't you just use

file_get_contents ('http://www.mysite.com/friend.php?id=0123456&af=60067');

This should simplify it so you don't have to use sockets.

hi stasonis,

yes file_get_contents does work sometimes but I find that it doesn't work whe i try and connect to certain servers.

Using fsockopen seems to be much more reliable.

The header is separated from the body of the reply by two CRLF's: "\r\n\r\n" so just get them string functions a twangin'

Alternatively, and very messily I might add, you could also grab the content length using a RegEx and just take that many characters from the end, ie.

    $regex = '/Content-Length: [0-9]+/';

$matches = array();

preg_match ($regex, $string, $matches);

$count = trim(substr ($matches[0], 16));

echo substr ($string, -$count);

But drakla is right, probably much easier to locate the two CRLFs
