只要用于只需要发起请求，不需要接收响应值的，因为接收响应值浪费大量时间

$url = 'http://tencentlog.com/stat/report.php';

$post_data = array();

$this->http_request($url,'POST',$post_data);

    //发起http请求之后立即关闭访问信息    function http_get_host_ip($hostname){if($hostname == 'tencentlog.com'){return '183.61.46.160';}else if($hostname == 'union.tencentlog.com'){return '140.206.160.173';}        return gethostbyname($hostname);    }        /**     * http 请求   - mayer     *     * @param String $url     * @param String $type  GET or POST     * @param Array $post_data     * @return false or String     */    function http_request($url, $type = "GET", $post_data = NULL)    {    $type = strtoupper($type);        $http_info = array();        $url2 = parse_url($url);        if(($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0){            return false;        }        //set socket timeout        socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,    array("sec"=>1, "usec"=>0));        $url2["path"] = ($url2["path"] == "" ?
