你能实现模拟POST提交登录http://bbs.lampbrother.net/ 这个网站吗??

无论你用什么方法都行?只要能写出代码,腾讯面试题啊

<?php $post_data = http_build_queryarray step => 2, lgt => 2, forward => , pwuser => hehe@163.com, 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; $cookie_file = dirname__FILE__./cookie.txt;
touch$cookie_file; $ch = curl_init;
curl_setopt_array$ch, array CURLOPT_COOKIESESSION => true, CURLOPT_RETURNTRANSFER => true, CURLOPT_HEADER => false, CURLOPT_VERBOSE => false, CURLOPT_COOKIEJAR => $cookie_file, CURLOPT_COOKIEFILE => $cookie_file, CURLOPT_POSTFIELDS => $post_data, CURLOPT_POST => true, CURLOPT_USERAGENT => $user_agent, CURLOPT_URL => $login_url,
;
$response = curl_exec$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 , $login_status; /* functions */
function detectEncoding$str { return mb_detect_encoding$str, arrayUTF-8, CP936, BIG5, ASCII;
} function convert2gbk$str { return convertEncoding$str, CP936;
} function convert2utf8$str { return convertEncoding$str, UTF-8;
} function convertEncoding$str, $to_encoding { if $to_encoding !== $encoding = detectEncoding$str { $str = mb_convert_encoding$str, $to_encoding, $encoding; } return $str;
}
