PHP auto login Facebook via Curl.

The following code shows the trick on how to login your facebook via PHP Curl:
  

<?php

// script name: login_to_facebook.php

// coder: Sony AK Knowledge Center - www.sony-ak.com



// your facebook credentials

$username = "----";

$password = "-----";


// access to facebook home page (to get the cookies)

$curl = curl_init ();

curl_setopt ( $curl, CURLOPT_URL, "http://www.facebook.com" );

curl_setopt ( $curl, CURLOPT_FOLLOWLOCATION, 1 );

curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 );

curl_setopt ( $curl, CURLOPT_ENCODING, "" );

curl_setopt ( $curl, CURLOPT_COOKIEJAR, getcwd () . '/cookies_facebook.cookie' );

curl_setopt ( $curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)" );

$curlData = curl_exec ( $curl );

curl_close ( $curl );


// do get some parameters for login to facebook

$charsetTest = substr ( $curlData, strpos ( $curlData, "name=\"charset_test\"" ) );

$charsetTest = substr ( $charsetTest, strpos ( $charsetTest, "value=" ) + 7 );

$charsetTest = substr ( $charsetTest, 0, strpos ( $charsetTest, "\"" ) );


$locale = substr ( $curlData, strpos ( $curlData, "name=\"locale\"" ) );

$locale = substr ( $locale, strpos ( $locale, "value=" ) + 7 );

$locale = substr ( $locale, 0, strpos ( $locale, "\"" ) );


$lsd = substr ( $curlData, strpos ( $curlData, "name=\"locale\"" ) );

$lsd = substr ( $lsd, strpos ( $lsd, "value=" ) + 7 );

$lsd = substr ( $lsd, 0, strpos ( $lsd, "\"" ) );


// do login to facebook

$curl = curl_init ();

curl_setopt ( $curl, CURLOPT_URL, "https://login.facebook.com/login.php?login_attempt=1" );

curl_setopt ( $curl, CURLOPT_FOLLOWLOCATION, 1 );

curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 );

curl_setopt ( $curl, CURLOPT_POST, 1 );

curl_setopt ( $curl, CURLOPT_SSL_VERIFYPEER, false );

curl_setopt ( $curl, CURLOPT_POSTFIELDS, "charset_test=" . $charsetTest . "&locale=" . $locale . "&non_com_login=&email=" . $username . "&pass=" . $password . "&charset_test=" . $charsetTest . "&lsd=" . $lsd );

curl_setopt ( $curl, CURLOPT_ENCODING, "" );

curl_setopt ( $curl, CURLOPT_COOKIEFILE, getcwd () . '/cookies_facebook.cookie' );

curl_setopt ( $curl, CURLOPT_COOKIEJAR, getcwd () . '/cookies_facebook.cookie' );

curl_setopt ( $curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)" );

//$curlData is the html of your facebook page

$curlData = curl_exec ( $curl );


?>

    I have a question, how to access other page right after login?
    this code doesnt give me the results of the request:

    $curl = curl_init ();
    curl_setopt ( $curl, CURLOPT_URL, "https://login.facebook.com/login.php?login_attempt=1" );
    curl_setopt ( $curl, CURLOPT_FOLLOWLOCATION, 1 );
    curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $curl, CURLOPT_POST, 1 );
    curl_setopt ( $curl, CURLOPT_SSL_VERIFYPEER, false );

    $curlData = curl_exec ( $curl );
    echo $curlData;


    Thanks again

  6. Never mind. Perhaps, there is no need to init the curl again. After login, you use the initialized curl to get the data.

    // scrape some data yo
    curl_setopt ( $curl, CURLOPT_URL, "http://www.facebook.com/ajax/shares/view/?target_fbid=410558838979218&__a=1" );

    $curlData = curl_exec ( $curl );

    Pls have a try. Thanks:)

  7. I have question about password. Since my password contains special character "%" and FB returned incorrect password(I am sure my password is correct). How do I solve this ??? It need encoding ???

  8. Brilliant! This code works great, thank you for sharing! Would it be possible to authorize a Facebook app via curl, too?

    i have added below code after your code php sdk for that but each time it will return 0 instead of user id

    // Create our Application instance (replace this with your appId and secret).
    $facebook = new Facebook(array(
    'appId' => 'app id',
    'secret' => 'app key',
    ));

    // Get User ID
    echo $userId = $facebook->getUser();
