  public static function curlPage($paramArr){      if (is_array($paramArr)) {          $options = array(            'url'      => false, #要请求的URL数组            'timeout'  => 2,     #超时时间 s          );          $options = array_merge($options, $paramArr);          extract($options);       }       $timeout = (int)$timeout;       if(0 == $timeout || empty($url))return false;       $ch = curl_init();       curl_setopt($ch, CURLOPT_URL, $url);       curl_setopt($ch, CURLOPT_HEADER, 0);       curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);       curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);       if(defined('CURLOPT_IPRESOLVE') && defined('CURL_IPRESOLVE_V4')){            # 避免首先解析ipv6            curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );        }       $data = curl_exec($ch);       curl_close($ch);    return $data;}
