Answer 1

First define these function to get an associative array containing the url header and content (see http://nadeausoftware.com/articles/2007/06/php_tip_how_get_web_page_using_curl):

/**
 * Get a web file (HTML, XHTML, XML, image, etc.) from a URL.  Return an
 * array containing the HTTP server response header fields and content.
 */
function get_web_page( $url, $params, $is_post = true )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "Mozilla/4.0 (compatible;)", // i'm mozilla
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
    );

    if($is_post) { //use POST

        $options[CURLOPT_POST] = 1;
        $options[CURLOPT_POSTFIELDS] = http_build_query($params);

    } else { //use GET

        $url = $url.'?'.http_build_query($params);

    }

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    $header['errno']   = $err;
    $header['errmsg']  = $errmsg;
    $header['content'] = $content;
    return $header;
}

try this to load the 'http://www.example.com/buy' after login is successful.

// after curl login setup
$exec = curl_exec($curl_crack);
if(preg_match("/^you are logged|logout|successfully logged$/i",$exec))
{
    // close login CURL resource, and free up system resources
    curl_close($curl_crack);

    $params = array('product_id'=>'xxxx', qty=>10);
    $url = 'http://www.example.com/buy';

    //use above function to get the url content via POST params
    $result = get_web_page($url, $params, true);

    if($result['http_code'] == 200) {
        //echo the content
        echo $result['content'];
        die();
    }
}
