$c = curl_init();
$url = 'www.bitsCN.com';
curl_setopt($c, CURLOPT_URL, $url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);

preg_match("/

$content=file_get_contents("http://www.bitsCN.com/");
$pos = strpos($content,'utf-8');
if($pos===false){$content = iconv("gbk","utf-8",$content);}
$postb=strpos($content,'
