新修改的 curl get，如果成功，返回的是一个数组，包含返回的http头信息和数据信息。如果失败返回false。
返回的数据结构可以去掉//var_dump($info);注释查看。
常用的如

$info['http_code'] //http状态码
$info['datas'] //返回的数据信息.

curl POST

	$headers[] = "Accept-Encoding: gzip, deflate, br";
	$headers[] = "DNT: 1";
  
	$headers[] = "Connection: close";
	$headers[] = "Content-Type: application/x-www-form-urlencoded";
	curl_setopt($ch, CURLOPT_POST, 1);
	curl_setopt($ch, CURLOPT_USERAGENT, $UGA);

	}
	$info = curl_getinfo($ch);
	$info['datas'] = $datas;
	var_dump($info);
	curl_close($ch);
	return $info;
}

调用:

$url = 'https://console.online.net/en/order/server_limited';
$pdata = 'server_offer=757';
$sdatas = curl_post($url,$pdata,'https://www.online.net/en');
echo $sdatas['datas'];

返回的数据结构可以去掉//var_dump($info);注释查看。
