hi!!
i wanna login to facebook using php curl method  ..i found a topic in this forum but found no code
i'm posting the code i've used ..i'm a beginner, so the code might be funny   
i've replaced palceholders (my_email and my_password) instead of my actual username and password..

Code:

<?php 

function initial_visit()   //just to store the cookies initially set
 {
$ckfile = "G:\wamp\www\cookie.txt";
        $ckjar = "G:\wamp\www\cookiejar.txt";

$ch = curl_init ("http://www.facebook.com/");
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");


    curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckjar);
        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
}

function second_visit()  //use the cookies acquired earlier to use here
{
$ckfile = "G:\wamp\www\cookie.txt";
        $ckjar = "G:\wamp\www\cookiejar.txt";
        $ch = curl_init ("http://www.facebook.com/login.php");
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");

$postfields = "POSTDATA=charset_test=%E2%82%AC%2C%C2%B4%2C%E2%82%AC%2C%C2%B4%2C%E6%B0%B4%2C%D0%94%2C%D0%84&version=1.0&return_session=0&session_key_only=0&charset_test=%E2%82%AC%2C%C2%B4%2C%E2%82%AC%2C%C2%B4%2C%E6%B0%B4%2C%D0%94%2C%D0%84&lsd=_XhNM&email=my_email&pass=my_password";

        curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckjar);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$postfields);
        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
        $output = curl_exec ($ch);
echo $output;
}

initial_visit();
sleep(10); // simply to mock a human donno if it's required  ;D
second_visit();
?>

Any help would be appreciated...

Haven't tried a 'botic login to FB yet ... looking forward to this one.

[java_freak]

well. it turns out to be a simple thing that i've failed to understand  ..phew!! took a lotta time..
anyways, thanks perkiset..
will be  back with more questions 

[perkiset]

well ... so what was doing you? Was it a straight HTTP thing or something that FB was trying to inhibit you?

my top tip list of stuff to get curl to work:

1. visit a site page first to get a cookie before trying to submit stuff / interact

2. take care to specify the right referrer

3. try turning on gzip compression - a lot of sites seem to use this as a form of browser detection / bot protection

Do you mean

Code:

    $header = array(
            "Accept: text/xml,application/xml,application/xhtml+xml,
            text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5",
            "Accept-Language: en, en-gb;q=0.8, en;q=0.7",
            "Accept-Charset: utf-8;q=0.7,*;q=0.7",
            "Keep-Alive: 300");

/* adding  "Accept-Encoding: gzip,deflate", somewhere ? */

I thing that's what herbacious meant.

On a related note, try Ruby Mechanize. The library handles cookies, redirects and more automatically. It is far easier to use than curl if you need to make multiple requests to sites, since it handles state.
