PHP Tutorial: Php crawl content of HTTPS

Direct use of file_get_contents, will be an error;

Program code $url = (https://xxx.com ");
File_get_contents ($url);

Error:
Program code warning:file_get_contents (https://xxx.com) [function.file-get-contents]: failed to open stream:no such file or dire Ctory in d:wampwwwgrabber_clientindex.php on line 3

It is possible to use the Curl method:
Program code $url = (https://xxx.com);
$ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, Curlopt_ssl_verifypeer, false);
curl_setopt ($ch, Curlopt_ssl_verifyhost, false);
$result = curl_exec ($ch);
Print_r ($result);
?>

The emphasis is on the following sentences:
curl_setopt ($ch, Curlopt_ssl_verifypeer, false);
curl_setopt ($ch, Curlopt_ssl_verifyhost, false);
