<?php

$post_data = http_build_query(array(
    'step' => 2,
    'lgt' => 2,    
    'forward' => '',
    'pwuser' => '[e-mail]',
    'pwpwd' => '123456',
    'question' => 0,
    'customquest' => '',
    'answer' => '',
    'hideid' => 0,
    'submit' => '',
    'jumpurl' => 'http://bbs.lampbrother.net/index.php',
));
$login_url = 'http://bbs.lampbrother.net/login.php';
$user_agent = ' Mozilla/5.0 (Windows NT 6.1; WOW64; rv:30.0) Gecko/20100101 Firefox/30.0';

$cookie_file = dirname(__FILE__).'/cookie.txt';

$ch = curl_init();
curl_setopt_array($ch, array(

$response = curl_exec($ch);
curl_close($ch);

$response = convert2utf8($response);

$login_status = preg_match('#<p[^>]*>您已经顺利登录</p>#u', $response, $match) ? 'success': 'failed';
echo 'login ', $login_status;
