Can't change user agent php curl

Question

I am trying to change the user agent by this code

 $ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_HEADER, 0);

$exec=curl_exec ($ch);

var_dump($_SERVER);

It is not working. I want to send the request as a mobile phone. Is this possible.

Answer 1

curl_setopt($ch, CURLOPT_HTTPHEADER, array("User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3"));

这对我有用，并且必须发布到NodeJs服务器，因为PHP的cURL默认情况下没有提供。
