直接用file_get_contents，会报错；
$url = (https://xxx.com");
file_get_contents($url);
错误：
Warning: file_get_contents(https://xxx.com) [function.file-get-contents]: failed to open stream: No such file or directory in D:wampwwwgrabber_clientindex.php on line 3
用curl的方式是可以的：
$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($result);
?>
重点是以下两句：
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
